These are items from a retiring collection! This is a set of 4 beetle (stag beetle) mycelium bottles! The capacity was about 800g! They have stains and scratches because I was raising larvae and adult beetles. Please understand that these are used items! Please refer to the photos for the size! If you have any questions, please leave a comment! Passing them on to the next breeder!! #beetle #clear case #clear slider #breeding case
