I tried a new watch strap with the pins provided but it was a complete failure. I ended up breaking them and putting in my old original pencils. The mistake was that they didn't put enough force on the holes. I could just bend my wrist and everything would fall apart. WristandStyle.com contacted me as my only concern was that the hole in the leather strap for the re-tracking pen would be a weak point in the future. If you buy this tape keep your old pens if you get the same results as me.
