This a well-worn, flattened box from an Irwin Microdial expansive bit.  I am listing it only because it is such a rare vintage nostalgic item.   FREE SHIPPING.

Shipping to USA only.  I ship only a couple times a week, so please don't be in a hurry.  I reserve the right to choose a shipping method that is the most economical.  I will combine shipping, so look at my other items.
