Buttonhole elastic is a clever way to ensure comfort and adjustability – a stretchy, knitted tape with evenly spaced holes for fastening a button to regulate the width of clothing or accessories. Perfect for maternity, children’s or protective garments, as well as a practical “extender” for trousers or skirts. Made from elastic fibres, it returns to its original shape and is available in classic black or white with a width of 20 mm. With Berotex buttonhole elastic, you get comfort, flexibility and an easy way to achieve the perfect fit!
