These are super cute. I didn’t realize when I ordered them that they were coming from UK. I’m in the US so it took awhile (3 weeks)to get them. I would suggest better instructions on application. I am new to using a CGM so I ended up wasting 3 patches before I got the 4th one on correctly. Perhaps you could add a QR code linking to an online instruction video? Otherwise the design is very cute and when applied properly it does adhere well and protects the sensor from being bumped or dislodged.
