I don't know the dimensions of the SAS tin, but this one comes out to 22.86 cubic inches (5.18" X 3.74" X 1.18"). It has quite a bit less room than my current PSK container (a huge altoids-type "arts and crafts" box from Wal-mart with over 28 cubic inches of space), but this one looks to be much more durable and waterproof also. I've been planning on removing some dated items (matches, etc) anyway, so it should work out very well.
