Winplus Alcohol Pad is made from a cotton-type material and saturated with Isopropyl Alcohol. They are sealed in individual packets to keep them sterile and moist until they need to be used. Suitable to clean an injection site before injection and also to clean fingers before lancing the site for blood draw. Winplus alcohol swabs are thicker and softer than many other swabs, helping ensure reliable site preparation for safe, hygenic insulin injections. They are also appropriate for other household uses.
