Finger Traps are woven tubes that are a Tier 2 incentive won upon completion of 25% of a refiner's file. The way you use them is insert one finger from each hand into each end of the tube. Pull as you might, you cannot escape the double prison. You must relax and let one finger out after the other to foil the trap. They are mostly status objects though Harmony Cobel seems to enjoy pulling on them when she is pensive.
