LastSwab Original refill contains one Original LastSwab Rod. It can be used to refill the case, when the initial swab has run its course.. Sustainability. We use 100% Recycled Ocean-Bound Plastic for the LastSwab Beauty Trio Pro box. The swab rod is made of fiberglass and polypropylene, a plastic that requires much less energy to manufacture and produces the lowest carbon dioxide emissions compared to other types of plastic. The tips are of high-quality TPE (soft thermoplastic material). This is so it can last as long as possible. The absorbent tip is made of 30% short cotton fibers that cannot be used for clothing and is therefore a surplus material and 70% wood fiber. They can be composted in the garden. Our packaging is made from either FSC-certified cardboard or Cradle to Cradle. Both organizations make high demands on a number of environmentally burdensome processes and are both "best in class" when it comes to sustainable packaging.
