I just recently bought a container i thought was suitable for my terrarium but realized it had too many air holes/openings for what I'm going for.

I am starting to raise isopods and want to be able to have a humid environment for the exotic plants I'm putting inside, so air and water leakage doesn't help, so a no to wardian cases I guess :((

I know I could go and thrift a glass jar but i don't think it will be big enough, and I want enough space to have my bugs be able to roam and for me to be able to put multiple plants in there as well as bark and accesories. What I want is a more square/rectangular container that can be place on a desk or table and clear enough to see everything going on inside. The majority of containers I've seen like that are either wardian cases (which still have too many openings in them and leakage) or containers that go for 100-400 bucks a piece. I really just wanted this to be an affordable project but it's very hard to find the specific container i need without going through tons and tons of the same kind of listings on etsy, amazon, and ikea that are either not what I need or completely out of my price range. Where is a good place to find a container like this without it being crazy expensive?
