This is a hexagonal spacer that I used for a tile backsplash. All the stores were out of them and I needed a lot. I believe it's a 3/8 inch spacer. The spacer is meant to not be removed and sit within the grout line. Make sure that they are pressed down as far as possible so they don't show after you grout. Hope this helps someone complete their project.
