The bra extenders are made of polyamide and elastane with three adjustment possibilities to extend the underbust measurement for bras. They are simply hooked between the two ends of the bra. Due to the additionally processed elastic band and the seam-free processing, favourite bras that have become too tight can be worn again very comfortably. In the Prym range, the bra extenders are available in 5 different widths between 20 mm and 75 mm with up to 4 hook eyes per row in 4 different colours. They are tested for skin tolerance and are washable up to 40 degrees.
