Glues have an optimal shelf life of approx. 6-10 months. Hence, to prolong storage life we recommended our clients to keep the glue in a cool place like in a refrigerator. However, if the glue is stored in a refrigerator, wait about an hour before you use them for eyelash extension. The glue once opened will last for up to max 3-6 months. Here at our online store, you will come across a range of glues. Safe, durable and powerful as a bonding adhesive makes them the best choice for professionals to use for their eyelash extension glue procedures.
