Get them while you can

Sharpie does work for added personalization

but a friend has a rainbow one that is looking mighty sharp still after a few years

Fits the "default co2 aranet recommended in covid cautious spaces" aka this one

Works great clipped to a belt loop

Aranet4 Case Get them while you canI 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
