If you are looking for the perfect cord to use in your classroom or at home for arts and crafts projects, the Paracord Planet Rexlace Variety Packs are a great option. They are durable and flexible, so it is easy to use while making a variety of crafts such as bracelets, keychains, party decorations, and more. Each one is neatly held together with a small plastic band, which makes storing easier for excess Rexlace that can be saved for later. There is a holographic and a treslace option. Holographic is shiny and reflective while treslace is more solid without a reflective appearance.
