I am a plastic-fondler... I have just over 150 kits in my stash (including all subjects and eras), of which ~20 I have picked up for nostalgic purposes and which I won't build. Of those, only 9 are still in the shrink wrap... but many are still in their internal bags, unless i've picked them up second hand and the bags were already missing.
Now I just have to recover from the shock of having 150 kits in my stash... I knew it was a mistake to count...!
Cheers,
BC
