This is a hand toy that you wear on your fingers and play with. When you stick it out of 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. There are about 40 sets available, making them perfect for class reunions or gifts for friends. We generally ship within 1-2 days, but we are closed on Saturdays, Sundays, and holidays due to the post office's closure, so shipping will be on the next business day. If you are in a hurry, you can change to Rakuraku Mercari Delivery for an additional 100 yen, so please let us know before you purchase.
