Each pack is in a steam sterilised paper pouch which can be peeled open – ensures the sterility and integrity of each non-woven swab. The swabs are 4 ply and highly absorbent, absorbing up to 10 times their own weight of 30g per metre. The non-woven swabs are 100% particle and dust free. The swabs are non-sterile and ideal for light to moderate exudates.
