I have been buying Fiskars scissors for years, I love the spring loaded ones for fabric. Anyway when I started w/ the booms I got a 6 and 12 square up ruler and got fiskars b/c I liked their markings and b/c I have loved their scissors. Anyway the ink started wearing off so I got another 6 incher thinking I had a "bad batch" w/ the ink, and it was worn worse. Anyway it wore off quickly too, so I contacted the company a couple of weeks ago, and they sent me 2 replacement sets no hassle at all.
