A small glue roller, I use it when glueing paper. The roller itself is easily replaceable, see diagrams. Moving the clip will allow the legs to be pulled apart slightly, enough to remove and/or replace the roller. Moving the clip back in place again will lock the legs and will prevent the roller from falling off. The clip will lock in place.
