I purchased this line this year and used it for about 10-20 minutes. I only cut off a small amount for leader knots, etc., out of the 150m. It's a strong and firm line despite being 0.4, but it didn't quite suit me. Thank you for your consideration. This fishing line combines water resistance and abrasion resistance, and offers high strength in a 150m length. - Brand: DUEL - Model Name: Armored F+ pro - Size: 0.4 (7Lbs) / MAX 3.5kg / dia. 0.11mm - Length: 150m - Features: Waterproof / Abrasion Resistant Thank you for viewing.
