Pottery Barn Porcelain Pink Dot Tea Set Polka Dot Tea Party

DRL1011 #326

Really great pre-owned condition .  No chips or cracks. Little black marks on back of one saucer.  Thought it might be ink but it isnt.  It wouldnt come off.  Might be within paint factory flaw.  Not sure but unusual it wouldnt wipe off.  See pics for detail.  I will put that pic as last one.

Smoke free home.   Thanks for looking!

Edit...coming back since i photographed tea set.  With the bright lights shining directly on back of the one saucer, it looks like it could possibly be the glaze is thin in those spots (lines) that i thought might be marks that had gotten on the plate.
