A question for all you collectors of small things in blister packs (eg Hot Wheels, Matchbox or whatever). Do you keep them unopened with blisters intact, or do you try to carefully extract them without damaging the packs too much so you can zoom the models round the kitchen table?

I'm a 1:43 collector, so mine almost always come in boxes/cases you can unpack easily and then repack afterwards without package damage. The only exceptions are partworks in blisters, which I try to open carefully, but it's always obvious afterwards that they've been opened. But partworks are usually cheap'n'cheerful, so it doesn't matter too much.

So what do you do with yours? Are there cunning tricks to opening blisters without damaging them??
