These are the best spacers for the money! We do a lot of tiling, so I know they sell the same systems in stores for hundreds of dollars, which is crazy. This is the thinnest pad I've found on the market. We refill 2-3,500 packs each month and reuse the wedges 3-4 times until they're gone. It's also good if you need to stack a bunch of used ones together at the bottom of your starting wall to align with a bunch of 8's or so, you've got the first row level.
