This is a magnifying glass exclusively for participants of the Sumitomo Pavilion tree planting experience. It's made from the same material as the exterior walls of the Sumitomo Pavilion, utilizing "Sumitomo's Forest Cedar" trees planted in 1970 (Showa 45), the year of the Osaka Expo. Please be aware of initial scratches. It has only been opened, but if you are concerned about minor details, please refrain from purchasing.
