Non-brand silicone band for trumpets. Also for cornets. Slightly shorter and firmer than Yamaha's genuine product. Perfect for those who find Yamaha's too loose. I've started using it myself, and it has a good tension, so I personally prefer this over the Yamaha genuine one. To offer it at a low price, it will be sent by regular mail, so there is no compensation. Please be aware of this. We also have advantageous multiple sets, so please inquire. Thank you for your consideration. 【Attention】 We will refuse purchases from those who cannot rate immediately after receiving the item. We may respond with a rating in some cases. However, this does not apply if you have explained the situation in advance. Thank you.
