This is a hand toy that you can wear on your fingers and play with. When you stick it out from your sleeve, it looks like your hand has shrunk, which is fun. Additional sets are available for +200 yen each, starting with the second set. From the 10th set onwards, additional sets are +50 yen each. We have about 40 sets, so they're also recommended for class reunions or as gifts for friends. We generally ship within 1-2 days, but we are closed on Saturdays, Sundays, and holidays, so shipping will be on the next business day. If you're in a hurry, you can change to Rakuraku Mercari Delivery for an additional 100 yen, so please let us know before you purchase.
