The "Hatch" pen was designed to take advantage of the innate properties of brass, and its remarkable ability to self sterilize. Within a few hours of contact with brass ions, any bacteria or microorganism dies. While this effect is not new and the concept is centuries old, we don"t currently utilize the material"s enormous potential. This antiseptic quality lends itself perfectly to situations where hygiene is priority, including the medical profession. To further highlight the unique qualities and benefits of using this type of tool, the etched graphics relay some of the story or the reasons behind it. The hatched pattern is an abstraction of cell structure. The gradient of hatch variation can be symbolic of growth or infection bt overall it demonstrates organic change. In addition to its scientific appearance, the hatch pattern and random layout are also representative of a patchwork quilt. In this way, the graphic demonstrates the function the brass material by stopping infection at the cellular level, while it also appears comforting and safe like a sewn heirloom blanket. Designed by Karl Zahn in 2013, from Acme Studios, USA. The pen comes with one black roller ball refill. Artist"s signature is engraved on the cap band and "ACME" is on the clip. It is presented in an black ACME metal box with a black sleeve and ACME literature.
