The Nuvan ProStrips are not individually wrapped. There are 12 strips inside the foil packet/envelope. If all the strips contained in the foil packet aren’t used, contain the remaining unused strips in the foil packet. Squeeze out as much air as possible from the foil packet, fold over the opened end at least twice and seal with tape to sufficiently protect your unused Nuvan Prostrips. The shelf life of Nuvan Prostrips may be diminished by as much as a month or more if left unused. It is not recommended to store Prostrips in zip lock plastic bags. The efficacy of Nuvan Prostrips is better protected in a foil-lined packet.
