Accessories for insulin pens and vials, sorted by what you need: keep your insulin cool, carry your pens, protect your vials and needles, or give your pen a new look. Kaio-Dia cooling wallets and cases fit disposable pens such as FlexPen and KwikPen, reusable pens such as NovoPen Echo, HumaPen Luxura, InPen and JuniorSTAR, and standard insulin vials.
The Dia-Cool keeps your insulin pens cool without electricity. Soak the cooling insert in cold water: it cools by evaporation for 48 hours or more depending on ambient temperature, up to 12 °C below the air temperature. Sizes for 1, 2, 3 or 4 pens.
Carry your pens with the rest of your kit: the Dia-PenCase and Dia-MidiCase hold pens and a glucose meter, the Dia-PencilCase adds a cooling insert, and the Kaio-Emergency Pack takes two insulin pens or two EpiPens with its own cooling pack.
The Kaio Vial Tube protects your insulin vial from knocks in a bag or pocket. The Dia-Needle Tube stores up to 4 pen needles safely.
Personalise your pen with stickers cut to its exact shape.





48 hours or more depending on ambient temperature, up to 12 °C below the air temperature. To reactivate it, soak the insert in cold water again.
Count your pens: sizes exist for 1, 2, 3 or 4 pens. The 2-pen size also takes 2 vials, the 3-pen size 5 vials and the 4-pen size 8 vials. For vials or eye drops only, choose a vial wallet for 1, 3 or 4 vials.
Each sticker set is cut for one pen model. Pick your pen below to see only the stickers made for it.
By hand, at 30 °C maximum.
