Used stamps exchanges.

not as bad as https://100stamps.club/stamps/RO-130

for a gentlemen question... at least this should be 4 star
I'm an amateur collector of stamps.

I guess this choice of stamps fullfill your wishes:

My collection consist of vintage small stamps and modern mushrooms, flora, fauna, sports, science, vehicles, space ... off paper stamps, mostly used and CTO's but few mint as well.
i'm mainly interested in Russian (including CCCP) and East European (Hungarian, Romanian, Poland, Bulgarian ...) stamps, but accept worldwide stamps as well.

@Szabolcs_H considering what you send you shouldn't expect to receive better

Anyway Laurent, he is having what he has at his list >> "vintage small stamps" for example... anyway, clearly, he is rating 3 because Tony, being generous, rated 4 star... again the same story.
You know what I think :)

He sent junk to me and I gave him a 4* rating. This is one of those collectors to stay away from.

Clean waste, definitive stamps. Rating 3 is perfect.

@Szabolcs_H how is that lot different from the one you sent yourself?
