These gauze swabs are made of Troge Absorbent Gauze BP. They are high absorbent and very kind to the skin. Due to the special folding technique the cutting edges are lying completely inside. This enables the user to unfold the swab to different sizes. Thus it is prevented that the fibre of the gauze adheres to the wound. TRO-STERISORB sterile swabs are extremely soft and extraordinarily permeable to air and steam.
