20 Pcs Insect Spider Terrariums Breeding Box Small Reptile Hatching Container Transparent Cricket Keeper Breeder Box Feeding Spider Cage with Lid for Scorpion Gecko Tortoise Centipede Tarantula

At .85$ a unit I am very happy to have enclosures I feel good about selling my jumping spiders in! I don't know why they were assumed to be acrylic by another reviewer because that's not what they claim to be. They are excellent for stacking and maintaining a large amount of (2-4 instar) jumper slings and I will be using these to sell off my lot of slings. I can see these being great for a lot of different types of small insects and arachnid. Thank you to all the sellers who make reasonably priced products for the spider/insect community! We need this stuff!

Good little boxes for slings.

These are very small and not very sturdy. Could be good for infrequent stationary use, but not adequate for transport or frequent use.

This type of enclosure is so much better to use than deli cups when it's time to separate baby jumping spiders! I love that the lid can stay in place while you open just the hatch for feeding and misting. I have a larger version for tarantula slings, and it's been great!HOWEVER, the first thing I did was to test the gaps and holes by placing a couple adult melanogaster fruit flies in an empty container to see if it held them securely. Within 2 minutes, one of the fruit flies had walked right out through an air hole. I think it will be okay for my jumpers, because they are slightly bigger, but obviously I can't have their food walking out. It might work fine for hydei, but melanogaster is a no go without reinforcement. I'm thinking I might tape over the holes and poke holes in the tape that are a bit smaller, just until the spiders are able to take larger food.UPDATE: I ended up waiting to use these until my jumpers were large enough to eat the larger hydei fruit flies. There's no way the spiders could escape, but I am still having problems with larger fruit flies getting out through the air holes! These enclosures would be so perfect if I didn't have to worry about the prey escaping.

i use these to transform my super worms to beetles... they work great

Not great for slings. The lids have a gap where the lift flap is and it’s big enough for slings to squeeze through. I had to modify it in a pinch with tape. Would have been perfect if the flap was flush. If you’re using it for larger critters and prey as a temp or travel home it might still work for you. Good price, decent quality.

Flightless fruit flies can get out where the door closes there’s a bit of a gap but it works great for a little bigger spiders.Bought some for my daughters school they are always catching observing and releasing bugs and critters

These work great for all the insects and reptiles and amphibians in my backyard
