The linen double buttons from Prym keep what they promise, because they can be used to close bed covers and pillows with button holes on both sides easily and without sewing. Buttonhole rubber bands can also be connected using the double buttons for laundry. Made of high-quality white plastic, the laundry buttons are available in diameters of 15, 17 and 18 mm. A pack contains 7 to 9 double sided laundry buttons - depending on the size of the buttons.
