After struggling with soggy tippet spool labels for years, OPST realized that there was a gaping hole in the tippet spool market: waterproof labels. They 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.
OPST fluorocarbon comes in 8, 10, 12, 16, 18 and 20 pound test and come 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
