These are prion cups made from Kunugi wood and Kawara mushroom substrate, suitable for Kawara species such as *Prosopocoilus auritus* and *Chalcodes tarantus*. These are self-filled and formulated with trehalose, soy protein, etc., to suit first instar larvae. I prepared a large quantity, but the number of larvae I obtained was small, so these are unused and have been stored. (Made on December 22, 2025) This is a set of 20.
