Our Zip Rubber Tiles are a larger tile that features a high level of color. Our Zip Rubber Tiles only come as center tiles, so you will have to cut them to create corner and border tiles. Our 8mm Strong Rubber Tiles have a little less color than our Zip Rubber Tiles. These tiles do come in corner, border and center tiles allowing you to easily create a finished floor. Our 8mm Strong Rubber Tiles - Designer Series have the highest amount of color which is why they are the priciest of the bunch. These tiles only come in a center tile, so you will need to cut them to create corner and border tiles. Our Eco-Lock Rubber Tiles have the same amount of color as our 8mm Strong Rubber Tiles, however they feature two removable edge pieces. This allows you to create border and corner tiles with ease, but it will not look as seamless as our 8mm Strong Rubber Tiles. Our Zip Rubber Tiles, 8mm Strong and Designer tiles all come from both coasts, whereas our Eco-Lock Rubber Tiles only come from the west coast.
