Hola Carlos,
thanks for your selection of stamps. As requested, I will remember what you sent me when the time comes and I will send to you. While the stamps you sent were all quite recent, they were almost all very common Scandinavian and Czech and Slovak Republic self-adhesive stamps (I had them all except for one). But you tried, and that is a big plus. Many people here send more than 100 stamps (just a few extra) in case there are damaged stamps included in error. Your sending included two Slovak stamps with short perforations, so strictly speaking you did not meet the requirement of 100 undamaged stamps as you only sent 100 stamps in total. But that's ok - this time.
I actually collect Spain and am always looking for reliable exchange partners. Are you interested? I can offer mainly Australia, Western Europe and Thailand in exchange. I have a Spain wishlist based on the Michel catalogue, and I am also on Colnect (profile: snowmark). Let me know if you are interested.
Regards
Mark
