First, they're Magic Pins, so you know they are sharp. Second they are in a nice sturdy storage case. They came just in time as I was working on a wall hanging and I needed them to mark my rows. The fact that you can iron over them and the letters/numbers don't come off is exactly what I need. I had purchased a different set that was cheaper, supposedly you could iron on and found out when you did the numbers came off onto your iron. Penny wise-pound foolish.
