We've created these Exclusive Bum Plugs for our Bikini / Underwear to integrate into the suits. A few people have asked to purchase our Bum Plugs made for the suits separate, so we created this listing. Our Bum Plugs CNC machined from solid aircraft grade aluminum, then hand sanded to a brushed satin look finish. These exclusive Bum Plugs feature a thicker base to accommodate the holes we machine in to attach the suits to. They Bum Plugs can also be use alone. Available Sizes: 1 1/8" 1 1/2" 2" 2 1/2" 3 3 1/2" 4"
