This device is very similar to the Ota Ring of Japan, with the primary difference being this device uses a stainless steel coil around the outer polyethylene ring. Triangular polyethylene center core with three curved spokes radiating out. Unlike other Chinese metal ring IUDs, this one came with nylon cervical threads.
