Permanent glue on wheels! To use this glue, you simply "roll" out the glue on the surface where you want to put your picture. After you've laid down the glue you have a few seconds to adjust the picture before it sets. The total length of the glue is 15 metres. It is transparent, and is, of course, free from solvents and harmful acids.

There are even practical refill bottles for when this dispenser is empty.
