Masterpiece 5mm Item Adapter

Are you disappointed that your Masterpiece Soundwave isn't able to grasp 5mm items without them falling out? Welcome to the solution. This product comes with two adapters that simply peg into Masterpiece Soundwave's hands; the adapters are easy to use, once they're in place simply slide your desired item into the convenient 5mm hole. These were designed for mp-13 (Masterpiece Soundwave) but are also compatible with mp-10 (Masterpiece Optimus Prime), mp-13b (Masterpiece Soundblaster) and mp-10b (Masterpiece Nemesis Prime) *Please note that there have been several iterations of Masterpiece Optimus Prime in the Masterpiece line but only the mp-13 variants are known to work with these adapters*
