Kendo Shinai Tsuba Stopper 38/39 For thick grip sizes. Hand-sewn by us, handmade. This is a high-quality hand-sewn finish, not machine-sewn, with no expense of time and effort. Made with 3mm thick rubber and an inner diameter of 28mm. Much more durable and long-lasting than commercially available products. We hope you'll feel a subtle sense of style, and that your daily practice will become more enjoyable! We made this with that thought in mind. * Because they are handmade, there are individual differences in the outer diameter. Please understand. If you want 2 or more, or multiple pieces, we will accommodate you in the comments section. Instant purchase without comment is OK. We can also make extremely thick tsuba stoppers. #Kendo #Shinai
