I agree with Dean Hoffman, those little packs are great for small projects and
the perfect solution to your preferred glue. However, most glue bottles can be
stored indefinitely by finding a right-size screw-on cap from other products you
use to replace the dispensing cap when not in use. Sealing out moisture and air
is not a dispensing cap's strength and almost none do it well.
