This shape, similar to the outline of a fedora or t-shirt, was argued in a 2023 paper by David Smith to be the first example of an Einstein tile, also known as an aperiodic monotile. This is a shape that can be continuously tiled with the same pattern never repeating. This listing includes twelve tiles with a two-tone design, which you can select from the menu. Each tile measures 2" across at its widest point.

I try hard to describe all my items accurately and to make sure the customer receives them quickly and in good order. But if you do have any kind of issue, please let me know and give me a chance to make it right before leaving neutral or negative feedback. Please also note that the handling time needed to prepare your order is included in the delivery estimate, and I am not able to offer expedited shipping. Orders for multiple items may require some additional handling time, and the shipping method may be upgraded for larger orders at no additional charge.
