The Everyday Shell

The bare minimum, done properly. Friction fits onto your CGM. Push on, go.

Not compatible with Armour, but we make Armour shells in this same finish.

Designed by a Type 1 Diabetic, for Diabetics.

In the box

The Shell — precision-printed in plant-based PLA, available in twelve colours.

A removal tool — slim and functional, made for taking your Shell off without damaging your CGM.

Which Shell fits my CGM?

We make four Shell sizes, one for each sensor we support. Pick the one that matches the writing on your sensor's box.

Dexcom G7 / One+ Dexcom G6 / One Libre 2 / 2+ Libre 3 / 3+

Your CGM ships at the same dimensions every time, so the grip is identical.

The friction-fit adapts to the CGM. No force required, no chance of damaging it. Slides over, stays put.

Will it still scan?

Yes. Phone NFC scanning works straight through the Shell. No signal interference, no need to remove anything before checking your readings. Tested with every sensor it's built for.

Material + care

Built from PLA, a plant-based polymer printed at high resolution for a clean, precise finish. Rigid. Lightweight. Holds colour beautifully.

Splash-proof — handwashing, light rain, sweat, all fine. Not built for submersion. Skin-safe — non-toxic, no harsh additives, comfortable against skin for daily wear. Not for contact sports — rugby, boxing, MMA, take the Shell off. PLA is rigid, not impact-absorbing.

Cleaning — wipe with a soft cloth and warm water with mild soap. Avoid isopropyl alcohol and harsh solvents, they can dull the finish over time. Dry fully before snapping back onto your sensor.

Storage — when it's not on your arm, keep it in the pouch it shipped in. Keep it out of direct sunlight and away from heat — car dashboards, radiators, hot windowsills. PLA softens at lower temperatures than other plastics.

Avoid — abrasive cleaners, dishwashers, prolonged heat, and forcing it onto a sensor that isn't its match.
