So ready to purchase them I saw that the ones for sale are not the square tiles we have. They are rectangular! Now, that's not horrible but I'd much rather have square tiles. A 4- Pack is $14.99. Good price but I'm not happy with the shape. However, maybe the rectangle ones can benefit our gam,ing set up when a square grid is too big to fit? Thoughts and tyhe link is below. If you can find square one splease post here and let me know. These are a gaming need of utmost importance.

We also have gaming mats which have been awesome. From a look i found really nothing that I thought would work w/ you currently have or would be a good replacement
