These reusable microfiber cloths measure 7" x 7", allowing your whole hand to fit at the back of the cloth while cleaning. They are perfect for ridding your home of dust, cleaning your glasses, or dusting off the screens of your electronics. Each cloth is crocheted by hand and made to order. They are machine washable and dryable, however, to increase longevity, I recommend washing them separately from other fabrics in cold water without any fabric softener. Disclaimer: Colors may vary slightly from pictures due to yarn originating from different dye lots.
