It can be installed in your preferred location on a breeding tank or plastic case with a glass thickness of 5mm or less. Commercially available wide cup insect jelly can also be placed directly on the food tray. (Food tray hole diameter: 38mm) If it frequently comes off, add more magnets. Up to 4 magnets can be added (2 on the food tray side, 2 on the fixing part side). No individual sales, no price reduction. Thank you. m(_ _)m
