Hinoki mat effective for mite prevention and deodorization for stag beetles and rhinoceros beetles. I used it a little during the summer for raising rhinoceros beetles. 200g (unopened) and 190g (opened). Total is 390g. The rhinoceros beetle has passed away, and I don't plan to raise them next year, so I'm offering it to someone who needs it. The natural wood scent is pleasant, so it can also be used for deodorizing shoe cabinets or in a gauze bag in the bath. - Product Name: Fuwa Fuwa Mat - Unopened Weight: 200g - Opened Weight: 190g - Application: For adult stag beetle and rhinoceros beetle care - Features: Mite prevention, deodorization, etc. Thank you for looking.
