I have 4 new tucks of Astra SP blades. I would like to trade them for Feathers or PolSilvers. I am not looking for a 1:1 trade. If it is fair I am all for it. Might consider something else other than blades but I don't need anything right now.
If you are shipping this few blades, I recommend taping them one at a time in a tile pattern to a piece of paper and sending in envelope.
Only way this is feasible or worth it.
If it weighs over an oz, add an extra stamp.
