The Wedding Sand Ceremony has become a popular way to celebrate the joining of two lives. This is a new trend that can replace the unity candle portion of the wedding ceremony and provides a keepsake that will last a lifetime. Wedding Sand is 100% natural and non-toxic. Our sparkling Wedding Sand may be used for play, in floral arrangements, tabletops, driveway projects, and pretty much anything you can imagine. Please test the PH Balance before using in aquariums. Each pound of Art Sand contains approx. 1-1/2 cups.
