I needed something to add to my new collection of router bits to cut pieces of wood evenly. They work great and are great value for money. My problem is the packaging they came in. They were almost glued into the holes and I cut myself trying to get them out. The holes are so narrow that every time I have to use them I have the same problem. I think I should be grateful that it gave me the motivation to design and build my router bit storage station just so I didn't have to use the box they came in.
