With the TLS SMART ECO tile leveling range, you can prevent the formation of level differences (jagged surface) between tiles. The ECO clips are made of premium quality recycled plastic, which in no way affects the quality of the tile leveling (it remainsas perfect as before). However, kicking or knocking out the tile leveling clips is much easier and more comfortable due to the material properties. A favourite entry-level product for professionals and hobby tilers, which copes with most of the tasks without a problem.
