6x4' Hex Grid GEO Mats in 1", 1.25" & 1.5" Hex Grids with either a black or white colored grid. We love the gaming industry and, even more, we love bringing innovative products to improve the gaming experience; the GEO Mats are the next TABLEWAR innovation to do just that! The GEO Mats are, most simply, a transparent gaming surface with a pre-printed grid on it. Once more, you can draw on the surface with wet-erase markers or grease pencils and easily erase the marks. Writing on the GEO Mats – The GEO Mats are made to be written on with erasable markers and grease pencils. We recommend you write on the non-printed side. We also recommend Wet-Erase Markers rather than Dry-Erase Markers; Dry-Erase markers can stain plastic if left on the surface for longer than a few hours. Wet-erase markers write easily and clean-off the most easily but also are prone to smearing. Grease Pencils provide an instantly smear-proof writing on the surface but require a little more effort to clean off the surface. These are our personal favorite to use. Cleaning the GEO Mats – We recommend cleaning the GEO Mats with water and a towel (paper towels are fine too). Baby-wipes can be particularly useful especially when cleaning off the grease pencil marks. Using a dry towel after the wet towel or wet wipes gives a dry surface that is ready to write upon again. Stronger chemicals, including glass cleaner, are not necessary or recommended. We hope you enjoy our product!
