I used to be really into handmade crafts, and I bought these at the accessory parts section of Joyful (a Japanese store) a while back. The cases were purchased at a 100-yen shop or a home center. There's a crack on the lid of one of the cases. The bead sizes vary. There are also T-pins, jump rings, and triangle bails for earrings! ★ To the artist, To the person who will use them *\(^o^)/*
