After struggling with soggy tippet spool labels for years, OPST realized that there was a gaping hole in the tippet spool market: waterproof labels. We set out to right this sad state of affairs. Not only are OPST's fluorocarbon spool labels waterproof, but the tippet itself is strong. How strong? Not super strong. Mega strong. What does that mean? You'll just have to try it and find out. Our fluorocarbon comes in 8, 10, 12, 16, 18 and 20 pound test and comes with convenient elastic bands to keep the tippet in check. 30 meters per spool. The diameters are:

8 pound: 0.235mm, 10 pound: 0.260mm, 12 pound: 0.285mm, 16 pound: 0.330mm, 18 pound: 0.370mm, 20 pound: 0.405mm
