PEAK’s Magnum Hex Stacker is designed with the same concept as our standard Hex Stacker but built magnum size to handle large bundles of hair for spinning and longer hairs such as bucktail. The opening at the top is 1.13 inches in diameter and the cavity for the hair is 3-9/16 inches deep. The base also works well for holding multiple colors of hair while stirring to blend color mixes. The non-plated aluminum body won’t build up static, so hair doesn’t cling to the tube. Both the top and bottom of the PEAK Magnum Hex Stacker are hexagonal so neither end will roll off your table.Do you need help?
