Gusket muffler. This was included in a lucky bag purchase, but I won't be using it, so I'm offering it at a lower price than the retail price. It is a new, unused, and unopened item. If there are any initial defects, please contact the manufacturer directly. Retail price is 2100 yen, and it has good reviews. I hope someone who will use it will purchase it. - Product Name: Padding Muffler - Color: Cream - Design: Diamond Pattern - Material: Padding material - Size: Baby size Thank you for viewing.
