Thank you for your feedback. We do manufacture our tile spacers in the USA. They are soft and flexible for easy maneuvering in the tile joints. For easy removal, use spacers vertically in traditional tombstone-style. They work well for all sizes of ceramic tile, porcelain, stone and marble. However, we do not recommend them for large format wall tiles 15" x 15" or larger. Please visit QEP to view our entire assortment of tile spacers including our T-Tile Spacers, Hard Leave-In Tile spacers and our various tile leveling systems.
