Thank you for viewing! ☆Celebration of Workshop Cleaning - Giveaway☆ I listed these once as materials for repurposing, but it's a bit complicated, so I'm selling them as is! Large: Diameter 21 cm, 6 jingles Medium: Diameter 18 cm, 5 jingles Small: Diameter 15 cm, 4 jingles All 3 are 4.8 cm thick. I'm not sure what kind of synthetic leather it is, but it seems quite sensitive to moisture. Because they are pre-tuned, tuning adjustments would be done by sun-drying, using a hair dryer, or spraying with water. Well, considering the diameters, a deep sound might be difficult to achieve! These are for toddlers, so the jingle sound is the main focus. This is a clearance sale. How about for your child? I'm not going to erase the Evergreen English Academy in the last image, haha.
