The best ones for glue are Master's Box and Unifier's Chest. You can get the Unifier's Chest by completing Traditions of the Celestial Empire. There are other collections that award both chests, but that one can be gifted.

Have a look at my Aids for the full list of collections: http://seekers-notes.wikia.com/wiki/Thread:1905 The chests are listed under Fixers; Chests.
