The NEW Pen fishing Rod Extreme® ultra light action rod is composed of high grade thin poly carbonate. Each tube has a small titanium ring which helps with stability & overall strength on the tips of each telescopic tube, right where it counts. The guides are crafted from titanium & fit over each tube like an insert. The tip of the rod is made from a solid piece of titanium oxide & the insert is comprised of aluminum oxide. The aluminum insert is PRESSED in at 110 lbs PSI to assure a solid seal. They are NOT glued in like the copy cat versions & cheaper rods. The aluminum insert allows for the reduction of friction & helps the line make a smooth transition through each titanium guide. It's GREAT when a fish takes the bait & runs. it won't fray the line or create friction & heat which will compromise the integrity of ANY fishing line you use. It is flexible, sturdy & very compact. It makes a GREAT Holiday or all around gift.
