Thank you for viewing. The bamboo spear muffler is missing (see photo). Instead, a group pipe and a three-stage seat (resin製) are included. The outer box is old, so there is some damage, dirt, and discoloration (see photo). The assembly diagram is also slightly discolored (see photo). The item will be wrapped in bubble wrap and shipped in a recycled cardboard box. If you are interested, please understand that this is an old product and purchase with no claims and no returns.
