This is a super strong fletching tape is transparent in addition to being both heat and water resistant. It's 3mm wide and ideal for attaching feathers to wooden shafts. With not needing time to dry, like most glues, you can quickly fletch a batch of arrows. I have field tested this product for several years and I prefer it to using glue. Once the feather is taped to the shaft I dab a small drop of super glue to ensure the feather doesn't lift if shot into the ground. It also has the added feature that if the arrow is destroyed but the feather is in good condition, you can, if careful, peel the feather off to re-use it!!
