These molds work, as the headline says, better than expected. They’re surprisingly tough as well!However! Let me give you some tips, ok?1 - there 100% will be weird gaps and spaces on the ‘top’ if you don’t fill it really full after the lid is on.2 - you will get resin evvvverywhere when you try to overfill it, especially if it’s before the lids are on.3 - if you’re using a pressure pot, you need to make wells on the lid for the extra resin4 - the d4 are sharp as heck, watch your fingers!5 - air bubbles don’t escape well without pressureSo #1 &2 - if you’re letting these cure in the air or in a pressure pot, if they’re not overly full, you will end up with gaps on the top number. This goes along with #2, that it spills everywhere. My Tip: figure out how the lids go on first. Then fill the resin up to just underneath the lip the lid fits into. Let them sit a little bit, not forever, but so they get just a bit less drippy. With your gloved hands, slide the lid-tab into the notched area, then gently push down with one finger over the lid hole, and use your other hand to run a toothpick gently under the rim, so the lid pops into place. Then use a Pipette to add more resin to fill it all the way up.#3 Using a pressure pot? My tip: Once you have the lids on using the mostly-clean method I described above, take some Play-Doh or (some other kind of not very expensive clay type material) and make almost a mini volcano or cup shape on the lid, around the hole, and even onto the sides if you want. Don’t press too hard, it’ll squish all the resin out. Then add more resin into that well - when the pressure does it’s work, it will suck all that excess resin down into the mold. If you don’t add a well and some extra resin, you will likely end up with perfectly clear dice that are missing chunks on the top. I use Play-Doh soft sculpting air dry clay, about a pea size per mold.#4 - they’re all sharp, but no kidding, the d4 (pyramid) dice is SHARP. Very very pointy and stabby. I happen to like it, but I don’t let kids touch them.#5 While they may make a lovely sharp set of dice, the air bubbles don’t come out very easily without a pressure pot, so expect some micro bubbles or surface bubbles. What I’ve found works the best for the least bubbles is to heat the resin as I pour in a small stream. I pour some mixed resin into another container, and then I very slowly pour, and I aim a heat gun or blow dryer at the spot just before the resin pours out, to try to heat it so it’s super runny and air can escape easily. I’ll also stop and blow hot air into the liquid in the mold every few centimeters. It seems to work okay, but of route won’t work if you’re trying to do some kind of specialty pour. Also, the hot air can eventually cause your heated resin to seize up into a hockey puck in seconds, which is why I use two vessels, so I don’t ruin the big cup of resin, just a few grams at most.You can also try heating the resin in the mold after the lid is on, sometimes the bubbles pop out of the lid hole when I try that. Make sure to add more resin though!Bonus Tip #6 : fill a little bit of the mold and then make sure the resin is all the way into the sharp corners before you continue - they’re air bubble traps.Bottom line: They can be fiddly to work with, and work best with a pressure pot, but these are really nice dice molds. They make nice dice, and the molds are rugged. Bubbles are the biggest issue, and that can be managed with technique and practice.

Work very well

About a month ago I had purchased this product because I was interested in making dice and wanted to try a manufactured mold instead of my first silicone one. This set of dice were made for my brother's and sister in law's wedding anniversary since they love boardgames. It only took me six or so tries of experimenting and figuring how exactly to use this mold, to produce a 'nearly' perfect set. Got to say, most errors are due to human error and not necessarily the design of product.*I did not use a pressure pot or deep pour resin for these dice.*I used crystal clear by Craft Resin + mica powder + gold paint for the numbers.*Problems include:(1) 4D Dice sometimes comes out of the mold with a broken or missing tip and it's mold is easily tipped over. {TO FIX THIS ISSUE, gently plunge a tooth pick down the center of the mold to the bottom tip. Swivel the pick back and forth and repeat, making sure to touch the tip. This releases trapped bubbles and 'injects' resin to the tip.(2) Bubbles often get trapped under the lids resulting in voids. {RESULTING IN THE NEGATIVE COMMENTS}(3) Using the included droppers makes the dice worse and results in more bubbles.*Tried Solutions Resulting In Dice Shown:(1) Don't use the droppers, they have a tendency to push air into the molds resulting in voids.(2) Mix your resin together for about 8-10 minutes so that it activates completely and then slowly pour resin to the top. The resin should slightly buldge into the space where the lids attach. (Some Resin will seep out when the lids are placed on.(3) Wait about 1 hour to 1 hour and 15 minutes before placing lids on. During this time, the bubbles will rise to the top of the mold. Check about every 20 minutes or so for bubbles. If bubbles are present, pop them with direct heat using a lighter - I used a long tip grill lighter. Waiting this long gives the resin a chance to bond and become more gel like while allowing bubbles to rise to be popped.(4) Carefully put the lids on each mold, being careful not to push down on them (especially in the center). Instead use a tooth pick to push the edges of the lids into their proper location.(5) Turn upside down quickly and place onto a flat surface. This is the only way I could get things to work (although a pressure pot may erase the need for this step). Wait about 10 minutes and check the bottom of the molds for bubbles. They should be noticable white or clear circles rising to the bottom. By this point your resin should be curing well and not be as runny but rather sticky.(6) Quickly flip your molds right side up and place back on the table. Some resin will have leaked out. Pour resin slowly and gently into the vent holes on each lid. Hopefully you have extra resin remaining or feel free to make a little more. The resin will be difficult to work with but should still pour, but at a thicker consistency.(7) Wait a few minutes to see if trapped bubbles rise through the vent hole. If so 'gently' or with very little pressure squeeze the mold to slowly move the bubble to the surface. Then pop with lighter or move out of the mold with a tooth pick. Gently release pressure so as to not lose a lot of resin and not suck air back into the molds.(8) Wait about 24 hours for your resin to cure or whatever your curing time is.(9) Pop your dice out of their molds and examine for bubble holes. They can be filled with a small amount of fresh resin if needed and then sanded off after curing.(10) Wait till the next day and trim flashing and sand + polish once your dice fully cure.*It's a lot of work and dedication, but totally worth it in the end. Not every die will necessarily be perfect, but keep trying and it will get better. This took 6 or so tries.

It's a really great idea. I'm having issues with getting all of the sides to match. The 6-side dice has 2 corners that are rounded and the rest are sharp so that isn't useful.

I got my husband these for his birthday because he has recently gotten into resin. They are not the best quality and a few need to be supported to be used, but overall they're not too bad. The biggest thing we're dealing with is large air bubbles under the lid. But the more he tries, the better they're getting. The biggest peice of advice I can give with these molds is: FOLLOW THE DIRECTIONS THAT COME WITH IT!

I was so excited to make some dice, when I originally got the molds I checked the molds quickly to make sure they all had lids with them because I had seen reviews that said they came without them.As I was getting them out and getting ready to cast some dice I noticed a few issues. On the D4 I had pulled out the numbers on the lid did not line up with the numbers in the mold if I line it up with the notch in the right place.If this were the only issue I wouldn't be too upset. Mistakes happen and you can easily cut the notch to allow you to line the lid up properly. But it wasn't the only problem.The font on a lot of the lids did not match the font inside their molds, and additionally many of the lids have parts sticking down into the mold from the hole meant to allow you to stick a needle into the mold to fill it with the lid on.Overall there is no way to use these molds to make balanced dice because the lids would cause large holes on one face of many of them.
