This is a hand toy that you put on your fingers and play with. It's fun because it looks like your hand has shrunk when you take it out of your sleeve. 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 15 sets available, so it's also recommended for class reunions or as gifts for friends. Shipping is generally within 1-2 days, but shipments will be made on the next business day on weekends and holidays as the post office is closed. If you're in a hurry, you can upgrade to Rakuraku Mercari Delivery for an additional 100 yen, so please let me know before you buy.
