Aranet4 Case and are not sure ifI have been using this same style case for 3 years now, and finally can offer a few to y'all :) This has been instrumental in making sure I take my co2 monitor everywhere for those sweet sweet datas. Works great clipped to a belt loop, or a bag. Comes with my preferred NiteIze carabiner that makes sure you can clip and unclip the case without any risk of it falling off the carabiner. Nice! Case is 3D printed white TPU (a flexible plastic). Sharpie
