Purchased at the UNiBO museum shop at the JAXA Tsukuba Space Center. It's a very small globe puzzle keychain ☆ I opened it and assembled it once, but it was surprisingly difficult despite its simple construction. While stored at home, one piece of the puzzle split in half. Please check the image 5. Please purchase this item if you understand the above! (Currently glued with instant adhesive) You can customize the key ring part by combining it with your favorite key ring! There is no package or instruction manual. I will ship the pieces unassembled. 【Size】 Globe diameter: Approximately 4cm Approximately 8.5cm including the keychain part #GlobePuzzle #EducationalToy #Keychain #JAXA
