This is a cleaning swab for wind instruments. Please note that the fabric is a bit thick, so it is not suitable for trumpets or cornets. It may be suitable for clarinets, etc. There is a weight at the end of the string. The length of the string, including the weight, is about 55cm. Since it is a non-brand product, we are able to offer it at a significantly lower price. To offer it at a low price, it will be sent by regular mail, so there is no compensation. Please understand. Thank you for your consideration. [Attention] We do not accept purchases from those who cannot provide an evaluation immediately after receiving the item. We may respond with an evaluation in some cases. However, this does not apply if you have explained the situation in advance. Thank you for your understanding.
