Just got mine in the mail. Like others I couldn't get mine open even with the instructions. It's
deceptive.
My thoughts are - remember it's probably been sitting on a shelf for a long
time. The box has a bit of a varnish on it that might be keeping the secret stuck. I banged mine a
little bit around the seam and it did open. Then I noticed the secret is very tight on mine and I
may have to sand a tiny bit to make it move more freely.
I'm gonna play with it a bit more
to see if I'm just inept but it is so tightly sealed I honestly would not have been able to open it
if I didn't have the instructions - after that, yes it's simple enough to do with one hand without
being seen.
Quality box for the money. Will probably ding mine up a bit to look old. Might
buy another to do some sort of trick. I'd rather have two now and it's cheap enough that I'm happy
to do that.
Buy this thing.
