This is an optional MIP Metric Wrench Wraps Set. At one time or another, we have all had difficulty telling our MIP wrenches apart at a quick glance. Well, MIP has an elegant solution for that - color coated wraps for each size of every MIP wrench! It's simple, easy, and effective; just clean the applicable area (contact cleaner), apply the wrap around the shank of the tool, then slide the clear Jimmy over the wrap. Wallah! Instant color coat recognition! The beauty of this product is that every MIP shank since the beginning of time has been the same size so the product will be applicable to them all.
