Prevent moisture from accumulating in the holes and clogging up your salt and pepper shakers. The flip-top lid seals tightly to keep moisture out while little prongs on the inside keep the shaker holes free from build-up. Easy one hand operation allows you to flip the tops open with a flick of your thumb. Attractive retro glass shakers go from cupboard to table to picnic blanket. Set of two, each 3 1/2 inches high.
