I first tried CD boxes to store them in, it was unsatisfactory from the very beginning, I was always afraid that one would fall out (there is always an "open" spot ). The Cd's are on the flimsy side, and have to be replaced after a time, and they just weren't big enough.
It was getting very frustrating finding something will hold up for the long haul and allow me to store all my stamps where they are readily available.
These ridged,clear, hinged boxes measure 4x6 and are 1/2 inch thick, they open flat which allows me to use the stamp and place the "dirty" one on the left side, if I don't clean them immediately like you are suppose to (a bad habit of mine).
These boxes will hold two 4x6 clear stamp set or one 8x6 set. I am getting ready to unmount my SU sets. A white label at one end will make it easier and much faster to find the set I want to use.
The boxes can be found at Flourishes and come in a pack of six, which will hold twelve 4x6 sets.
