10 pieces/white box, 10 fishing lines with 1 large box. Material: PE Craftsmanship: 4-piece Color: Yellow/Blue/Red/Grey/Green High-Quality Green Label Product specification grids: 10 rolls/box Specification box: 62*41*35cm, 240 rolls per box 100m 4-strand single color 0.4#-10# 1. High-tech weaving technology adopts round spinning technique, ensuring uniform and fine thread diameter for smooth appearance 2. The smooth high-quality PE line is more slippery, reducing friction during casting. The line quality is good, decreasing the resistance of fish in the water 3. Smooth and Anti-Tangle Cord Body, Soft with Zero Absorption, Round Textile Technology, Anti-Tangle 4. Stronger pulling force, both in terms of flexibility and gloss, extremely strong pulling force 5. Flexible and smooth without fraying, zero memory, no fraying, more sensitive in passing fish currents, strong tensile strength and wear-resistant, soft line body that doesn't damage the guide ring 6. Non-extended anti-static waterproof high-waterproof special resin with excellent waterproof effect; the thread body becomes thinner and more usable after use Fishing Line Maintenance 1. After each fishing session, promptly wrap the clean fishing line gently on the reel, trying to keep the line loose and not tight. Prolonged tension can cause the line to lose its original elasticity. 2. It's better to choose a round winder; square winders have right angles on all sides and can be placed for a long time.The strength of the fishing line decreases at bends, and the released fishing line can get dirty in the water used for fishing. It should be wiped clean with a cloth because the water quality in fishing waters contains many impurities including a certain amount of oil, salt, alkali, acid, and other components.If you don't dry the water containing these components, the cable will lose strength due to corrosion. 3. All fishing lines should be stored in a dry, dull, and pollution-free place to prevent moisture damage and aging. 4. When going out for fishing, wrap the fishing line with a line winder and do not place it together with other items to avoid scratching the fishing line, especially not with grease. If you notice that the color of the fishing line changes, fades, turns yellow, or becomes brittle. This indicates that the fishing line has aged or is starting to age; it should be replaced promptly. Don't risk it and leave the possibility of line breakage and lost fish.
