Currently in high demand and difficult to obtain, this is an ECHO cello endpin stopper, non-slip, maple wood, handmade. I purchased it after seeing Daiki Miyata's introduction and the Tokyo Cello Ensemble using it, but I've decided to sell it because I have one I always use. I only tried it for a short time, for about two days. I have included photos, and if you have any other questions, please ask in the comments. Here's the product description: Craftsmen in a Japanese workshop make each one by hand, matching the material, so it may take time to produce. "Echo" is a cello endpin stopper hand-carved from maple wood, the same material used for the back, sides, and neck of instruments. Because natural maple wood is processed by hand, there are individual differences in the grain and subtle size variations, so please understand. We have not made a hole because it may not fit depending on the shape of the endpin tip. It is easier to stabilize if you insert it in the center of the main body, about 3cm square, but the tone will change depending on the location, so please insert it in your preferred position. The strong non-slip effect works on all floor surfaces, receiving the cello's endpin at the optimal angle and returning a rich sound to the instrument. Dust on the floor may adhere to the rubber on the back and weaken the non-slip effect, but it will be restored by gently wiping it with water. The included "spare non-slip sheet" is effective when washed with water and wiped dry. The rubber on the back is difficult to adhere, so it may peel off. If it peels off, you can repair it with silicone adhesive or use it by overlapping it with the included "spare non-slip sheet". Retail price: 15,800 yen
