Let the glue set for 24 hours before using. Note that this holder is not intended for use as a replacement for the bubble-wrap and Ziploc bag roll used in the standard 0.5 liter thermos with ice inside the thermos. Using this holder in that setup will cause the Byetta to freeze!

This holder is intended for use with the thermos filled with 40-degree water and the ice outside the thermos. It could also be used as a general protective holder in situations where the pen is stored in a fridge or other environment in the 36 to 46 degree range.
