D-rings or semicircular rings are shapely all-rounders, because they are perfect for bag fastenings or for adjustable straps, also for belts, clothing, rucksacks, key chains and many more uses. Even as a cool accessory, the D-rings are perfectly usable for bags, teen clothing or for handicrafts. The D-rings or semicircular rings are smooth polished hardened steel - for perfect mobility of belts and straps. The central joint of the straight edge is burr-free and fits tightly, so that nothing can slip in between. The Prym D-rings are available in different versions.
