These white and transparent, plastic linen buttons are ideal for overalls at work or home, aprons, and bedsheets, since such clothing often needs to be hot washed at 95 degrees. However, these durable buttons can also be used universally thanks to their neutral look. They are both ironable and mangle-proof and can be dried in a clothes dryer. Prym offers these linen buttons with two sew-on holes in sizes 15 mm, 17 mm, and 18 mm. One package contains 14, 16, or 18 buttons, depending on the button size.
