Perfect size for trading cards
I'm using these to make bulk packs of mtg cards to sell & also to organize some by mechanics or type. These bags zip/seal well and are durable for reusing. They make homemade bulk card packs feel more professional due to their thickness & look more professional due to the good fit. Individual cards and small numbers of cards fit & look good. But up to 50 cards will fit & the snug fit makes the bags look custom-sized & professional. The label is a handy feature too but can be turned to the back if it's not needed. I expect these will be a staple for the bulk card side of our little hobby business and should work well for sports/baseball cards and Pokemon cards, in addition to the MTG cards that are my focus.

Ziplock Bags 9x12 Inch 4 Mil Thick
Ordered the 9x12 inch 4 mil thick bags and I loved them! They are just thevright size for storing important paperwork the you want to protect. The 4 mil thick material makes them last a lot longer so you can reuse them especially if you are saving cards or paperwork like tax records. Definitely worth the money just baause of the protection they provide.

Good Quality, but not what I needed
These didn't work for my intended purpose as the size was slightly off for what I needed. However, they are very durable bags and would be great for organizing a lot of things. The value for this pack was good, and they have a nice uniform look with the ability to label them built in.

Wonderful for rooting plant cuttings
Perfect for planting cuttings. I saw this on YouTube, it's genious. Fill them with 1/2 peet & 1/2 perlite. Insert the geranium cuttings & water. Seal tightly & watch thte roots grow. Easy was to share cuttings.

Perfect for diamond painting storage of beads
I have continued to order these bags for my diamond painting beads...they are sturdy & the perfect size. Also a great value for the money. You can label them or do as I do; I cut the number off of the bead bag & take it on this bag.
