This is an artificial pupation chamber made of sponge material that was previously sold in a Sheila case. It is for Bacheratta and Doronpa. There are scratches, but it is still usable. Please Google for details. Use it by placing it in an SS case and adding about 1 cm of water. The lid is also included. *8th image: One more has been added. #artificialpupationchamber #Bacheratta #Doronpa #spongematerialartificialpupationchamber #stagbeetleartificialpupationchamber
