I also make paracord bracelets myself, but I bought these with the intention of decorating them later. A bit of colorful microcord can give a simple cobra weave a completely different look, especially since there are many pattern variations and plenty of video tutorials showing how to do it. The size “S” turned out to be very small, so all three fit my 9-year-old son. For an average teenager, they would already be definitely too tight.
