The ERWIN M. LUSINI Refill pack ball fibers provides a practical way to restore the volume of your bedding products. This 200 g pack consists of white, high-quality three-dimensional hollow fibers made from 100% polyester, which help bring back the loft and support of pillows or duvets that have flattened over time. Measuring 40 x 40 cm and delivered in a simple bag, the filling is certified according to OEKO-TEX® STANDARD 100, ensuring the materials are safe for skin contact. To maintain the structural integrity of the fibers, this product should not be washed.
