QUALITY MATERIALS- Loose leaf ring is made of iron qualtity materials, strong and durables. Multi-layer nickel-plated steel rings prevent rusting, color unfading.
SIZE- 1 inch/ 25mm and 2 inch/ 50 mm diameter (outer ring), each size for 20 pieces loose leaf rings.
EASY TO USE- Convenient to use just pull to open and squeeze to close; the misalignment occurred after opening, because the binder ring itself did not use spring or other elastic devices, in order to make the bite tightness after closing more tightly, so this design was used.
WIDE APPLICATION- Binder Rings are suitable for loose-leaf, memo filing, key rings, scrapbook, binding recipe, photos, book, sample book, scrapbook,sample holders, contract or file.
