Coban™ Self-Adherent Wrap

This is only off-topic if you never get a road rash. I donated my 82nd pint of blood last week, not that much of a feat spread over 26 years, and asked for a Coban™ bandage to avoid the itchy rash that I used to get on my arm from the adhesive tape. The lingering rash with intense itching was by far the worst part of donating, edging out the inconvenience of skipping skating the day after. I've used Coban and store-brand imitations mostly after blood donations, but it's also good for large abrasions such as you get from falls.
