This is a pink leather choker featuring a stainless steel plated d and o-ring attachment. This pink d and o-ring choker makes a cute yet alternative gift for pastel goth, kawaii, harajuku and other alternative fashion styles. The pink o ring collar is suitable for fashion and play. The o ring comes in a variety of sizes from 1 to 2 inches. The models are wearing the 2 size o ring. The o ring measurement is taken from the inside diameter, so the 1 o ring measures 1 25mm from either side inside the o ring. The o ring thickness is 3-5mm either side so please add an extra 6-10mm to the inside measurement to get the full measurement and help decide which size is best suited to your needs.
