That's a great idea. Super useful in this day and age of standard versus metric and everything in between. Unfortunately, the labeling on the product was incorrect. Some were clear and easy to read while others were faded and very difficult to read. I'm wondering if after some use all the size tools aren't unreadable. Great idea, just overlooked it. If you can't read it, you don't need it. You can try another brand. SAD because the idea is great. love the steel cable that keeps them all in order. SO SAD!
