I'd like to trade 30/50 stamps at time; or for large amount or for stamps that have a high catalog value, I prefer to use on sending them by registered letters. Of course this is expensive, but it avoids some problems.

All stamps listed on my have lists are available on a first-come, first-served basis.  

If it is not differently specified , all the stamps that I have are in good condition.   

Please, don't send me damaged stamps, i.e. stamps that have tears, missing corners or stains.

My Lists are automatically updated at any minimal change.
