Aquarian duraDOTs add punch to your snare drum, cut ring from toms, and extend the life of any drumhead. This set includes two dura-DOTs: one 4-1/2" and the other 5-1/2". Each patch features a reusable adhesive backing that makes it quick and easy to experiment with new sounds in the studio or alter your tone onstage. Drummers appreciated the included storage sheet, which attaches to a lug screw to keep duraDOTs clean between applications and ready to use.
