Yes. The Shell is designed to stay on for the full life of your sensor.

You can apply it on day one and leave it in place until your sensor expires, including while sleeping and showering. The design is made for everyday wear, so you don’t need to remove it during normal daily activities.

If you ever have specific concerns about your routine, feel free to reach out, we’re happy to help.

The Shell features a precision pressure-fit design. It attaches by gently pressing the Shell onto your sensor with one hand.

To remove it, we recommend using two hands for better control, or asking for assistance if needed. Carefully apply pressure to release the fit without pulling on your sensor adhesive.

For a step-by-step visual guide, please visit our Tutorials page.

The Shell adds a small amount of weight and size to your CGM, so you may notice it slightly more than your sensor alone.

Each Shell weighs approximately 6–9 grams (about the weight of a loonie), making it lightweight while still feeling substantial and secure.

Most wearers adjust quickly (or don't feel any difference), and the Shell is designed for comfortable, everyday wear. It is light enough to forget, and beautiful enough to notice.
