❗ SETUP REQUIRED: PLEASE TAKE TIME TO SIZE THE BAND: The band is flexible and micro-adjustable. Cutting the band too tight can result in discomfort over long periods of use. Cutting the band too loose cannot protect the sensor. We recommend starting with a looser fit, then testing it out and adjusting incrementally for your perfect fit. The armband is designed to be easily taken on and off with the security clasp at your own discretion. NOTE: the total length (band and clasp) is 19 inches. 👍HIGHEST QUALITY FOR BEST USER EXPERIENCE: Freestyle Libre Sensor Armbands deliver the best user experience with their durable, waterproof, hypoallergenic food-grade TPU, their silicone and their stainless steel, produced to rigorous manufacturing standards for supreme durability and comfortability. 👍SLEEK AND CONTOURED DESIGN: Divoti Freestyle Libre Sensor Armband has a sleek and contour design that reduces the likelihood of the sensor accidentally snagging off. 👍DURABILITY AND COMFORTABILITY: Designed to fit and protect Freestyle Libre 1 or 2, and to eliminate any severe allergic reactions. Eliminates the need of any additional bulky and ugly adhesive patches. ❗ PLEASE NOTE: the armband is designed to be easily taken on and off with the security clasp at your own discretion. Due to its durability, you can easily take it off to wash and dry for the best personal hygiene. 👍FULLY ADJUSTABLE AND USER FRIENDLY: Once the band is trimmed, adjusted, and set up, simply line up and cover the sensor. You can easily take your Divoti Libre Freestyle Sensor Cover Armband on and off with the double security clasp. ❗ Please contact us before sizing if you have any questions.
