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. Tested in Polished Alumide. (Recommended) Due to the size of this product it is currently unable to be printed in any of the polished colored plastics, but I hope to soon remedy that.
