Hi everyone,
I've built up a pretty decent collection of S.T. Dupont lighters over the years, but I have far fewer original boxes than lighters. It really bothers me, so I'm looking to buy some original boxes separately.
The problem is that I've seen prices all over the place, so I'm not sure what a fair price actually is for an original S.T. Dupont box.
For those of you who have bought or sold them before, what would you consider a reasonable price?
Thanks in advance!
