After a simple cleaning, it has been stored in a dark place. As it was used, there are many stains, scratches, cracks, and dullness that cannot be removed. There are no particular problems with its use. I think it is suitable for small animals, amphibians, and humid environments. Acrylic cages can be expensive to buy, so please take this opportunity to purchase one. All the cages were purchased from stores, so they are well-made. Just to reiterate, it is not clean.
