Kyowa O'Band Svelte Corner Bands provide instant organization for anything sized B5 (8 in. x10 in.) to A4 (8 in. x12 in.). The clever holes allow the rubber band to hook over the four corners of a file, book, box, laptop, and more. Each 2-pack comes with one navy blue band and one red band that measure 8 in. flat before stretching.
O'Bands are made from natural vulcanized rubber and are ideal for bundling, sealing, and other use cases commonly found in the office or classroom. The most popular brand of rubber bands in Japan since their inception in 1923, these rubber bands are revered for their strength and utility.
