This colored caulk is made by Color Fast Ind. to match StarQuartz grout colors (per color chart above). Most are in stock but if not, please allow another 1-2 days for manufacturing. * Online color charts are meant to be a guide for color selection. Actual caulking color may look different as monitor calibrations may vary. * Please choose carefully as all caulk sales are final and can not be returned. Colors vary on different monitors but the factory formulates colors according to their specific guidelines of each grout manufacturer to ensure a close color match.
