This is a strap of "Satoko-chan," the younger sister of "Sato-chan," the character of Sato Pharmaceutical. I think it's a strap from the era of flip phones. It's probably a rare item now. Product Name: Pajama Satoko-chan Strap Features: Character goods with a Showa retro atmosphere, featuring an elephant motif. Usage: Can be used as a mascot to attach to bags, keys, etc. Material: Made of plastic, with a design like a small finger puppet. Thank you for considering purchasing this item. Thank you for viewing.
