Dip Tiles Spacers for Wall and Floor Tiles - 3MM (1000 PCS) Non-magnetic Line Level  (4 cm)

The main purpose of the product is to create asthetically uniform joints between tiles and to have better bonding with the grout along the tile joints. If the need arises where a single tile has to be replaced, then only that tile can be removed and replaced with a new tile without damaging the adjacent tiles.
