White sparrow with stars graphic was designed by Nina, one of Core One’s favorite tattoo artists. Smooth black Këpurthane material will never stretch, break, or absorb perspiration and odors. Reinforced pin-holes safely attach the strap to any instrument without the need for strap locks. Each design is hand silk screened on one of our adjustable 1.zero straps measuring up to 62” long x 3 wide.
