LOL!!! I bought the SAME ones!

The lids sure do suck... BIG TIME!!!
Do yours seem way too big for some of the containers? Pretty sad, eh?
I plan to use mine in a lidless rack, so it's not a huge concern for me. In the mean time I have a few housing pre-shed colubrids in the incubator with lids and I just went through the stack of lids until I stumbled upon some that fit.
I would take them back but I already drilled a bunch of holes in them. :s Oh well, they're the perfect size container... just crappy lids.
