This is a hand toy that you wear on your fingers. When you stick it out of your sleeve, it looks like your hand has shrunk, which is funny. 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 it's also recommended for class reunions or as a gift for friends. We basically ship within 1-2 days, but we are closed on Saturdays, Sundays, and holidays, so we will ship 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.
