I have 100+ SOSes for sell, 4.5k each or best offer. Waiting for your pm
(I can also trade for treasure maps lev 3-5, 1 SOS for lev3, 2 for lev 4, 3 for lev 5).As a bonus to this transaction I include a working copy of Kal In Ex SOS Master (EasyUO), which I personally fixed to make it working in our shard, it scans all the SOSes from your backpack and then auto sails to the closest one, see the screen below:
