The Jaggerspinner is a solid brass or copper fidget spinner that can be used in a few different ways. single hand for excellent fidget action. Two handed for good long spin times and also but not limited to table spins. And all spinners made by me will also provide at least one other function. I have added in to the design some bottle openers just to add function to this unique form. Included with this Jaggerspinnerv1 is a ceramic hybrid bearing and 13mm caps. you can choose from brass copper and stainless steel press fit caps.
