Studded Spiked Breast Binder with Nipple HolesCombine beauty and pain with the Strict Leather Studded Spiked Breast Binder. This sturdy leather strap encircles the bust, with two studded leather disks placed directly over the breasts. The tiny spikes on the reverse side make for a biting reminder of who is in control. There are thoughtful cutouts to give you unfettered access to their sensitive nipples, and there are two buckles to adjust the size (and ouch factor!) in the front and back.
