PENTAX Pentax Lens Cap 49mm Set of wooden cups from Gato Mikio Shoten Perhaps designed to prevent heat from escaping, they seem to keep warm items from cooling down easily. I bought them because I liked their cute, rounded shape, but I haven't used them much, so I'm offering them to someone who will. Diameter: 6.5cm Height: 8.5cm Weight: 98g I am also selling other camera accessories. I will offer a discount for combined purchases. Please comment if you have any questions. #PentaxLensCap_Korosuke #LensCap49mm_Korosuke #CameraAccessories_Korosuke
