This is a kit for observing the ecology of ants. I bought it about 4 years ago for my child's summer science project, but I didn't use it, so I'm selling it. - Product Name: Ant Farm Discovery - Contents: Ant farm kit, observation container, set of tools - Warning: Contains small parts, not suitable for children under 3 years old There are no noticeable stains, and I think it's in good condition, but please refrain from purchasing if you are sensitive to used items, as it has been stored at home. Please understand that we cannot accept any claims after purchase. Thank you very much! Thank you for looking.
