※ I am sorry, but I will decline requests for price reductions. ※ I will accept requests for combined purchases of two or more items. You can get a 50 yen discount per item. This is only the cap for the Pet Trick, nothing else is included. The cap is unused (8 pieces)! This is a refill for the Pet Trick. It's a very good value refill. Since it's a refill, there are no special instructions included. To be honest, it's a hassle to set up every time you do a show. You suddenly have to do something. The gimmick is gone. ...etc., it's a convenient refill for various situations. It's a plain white cap. It can be used with most plastic bottles. It's a one-time, disposable product, so I've made it an 8-piece set. Thank you for looking.
