Glue sticks are used with mounts. Rather than moisten the back of the mount, and risk water and/or saliva wicking into the mount, you simply use a glue stick on the back of the mount, since glue sticks are moisture free, and naturally acid free.
I too find this very intriguing. I always picture a glue stick as kind of stubby; are there dispensers shaped more like a pen to allow more control over the size of the contact area?
Are these safe to use on used stamps directly? Mint?
