The OEM Clipboard SAU21800 features a premium high-capacity clip that holds up to 1" of letter/A4 size paper. It is equipped with inch/metric ruler edges and is made from post-consumer recycled material. Assembled by adults with disabilities, this clipboard also supports a good cause, as Saunders donates 25 cents to City of Hope for every clipboard sold to help fund breast cancer research, treatment, and education.
