Sky S+ glue is a Korean-made popular glue. Ideal for classic and volume lashes. Note that cap colour does not indicate what type of glue is inside.
Unopened: Under 20% humidity (the lower the better), 6-16ºC
Opened: Tightly sealed lid, in a bag with a silica packet (to reduce humidity levels) in a cool dark place. Opened glues should be discarded 1 month after being opened, possibly sooner depending on storage conditions.
