latex #13 ink sac
So glad I was directed to this website. Bought a $179 Waterman 52 1/2v fountain pen that had an ink sac gone bad. Spoke to fountain pen nibmeister. Would have cost me $75 to ship and have it replaced. Instead I was able to order 3 #13 latex ink sac for $9.50 with shipping. I'm very happy I was replaced one and have two replacement sac for future use.....and it was still cheaper than having just one place. Lastly, VERY FAST SHIPPING.
