Finger Cots Protect from Contamination! They are rolled and Non-Powdered. Made super thin for excellent sensitivity. The fingers cots are used for blisters, abrasions & cuts. Finger Cots can be used to protect fingers from contamination, infection, apply medication, insert suppositories, and for many other uses where hygiene is necessary. Finger Cots also can be used to protect a lightly bandaged finger from moisture and dirt for short periods of time. Air circulation to an injury is reduced while wearing a Finger Cot, so it should be worn for only a short period of time.
