Storm insert tape, 1 inch, 50 sheets. Used for adjusting the thumb hole. You can use it as is, or you can cut it thinly for fine adjustments. Some people may think 1 inch is too thick, but if you cut it yourself, you can make it 3/4 inch and 1/4 inch, or 1/2 inch x 2... it's convenient(^^) (I cut it thinly for fine adjustments because my fingers swell and shrink a lot^^;) Instant purchase OK. You can also purchase 100 sheets. Please comment before purchasing if you want 100 sheets, as the price will be changed. (The price will be 1940 yen) Please refrain from negotiating discounts on this product only. m(__)m
