The Dual Tip marker will help consolidate markers in the operating room. The Dual Tip Marker (1422) has waterproof permanent Ink on one side and surgical skin ink on the opposite side. Thus, you can consolidate your surgical skin and label marker into one marker. This will help reduce waste and improve economics. The waterproof marker side has an ultra fine tip for writing on medication labels and the skin marker side has a Fine/Reg tip for marking skin.
