Say goodbye to dry pens with the Airless Pen No Dry Self-Erasing Ink Pen. Featuring a specialized internal cap, this writing tool prevents air inflow so ink never dries out. Additionally, Airless Pen uses a retractable silicon cap instead of a marker cap. This embedded cap produces a small vacuum space, keeping the water-based ink fluid. Similarly, you don’t have to take the cap off or put it on every time or remember to cover it after each use. In addition, Airless Monkey Pen and Board Marker are self-erasing writing tools. Utilizing innovative technology, the ink starts to fade in an hour. Likewise, the ink disappears completely in just a few hours, eliminating the need to erase. Suitable for all ages, the Airless Monkey Marker gives parents peace of mind knowing that the ink fades on its own. Airless offers up to 17 different colors to suit your creative needs.
