These felting needles are 78mm long specifically for needle felting. In the work area below the sharp shaft, the needle has a tip with fine notches that produce a barbed hook effect. These fine and coarse felting needles stand out due to the spacing and amount of these notches. Coarse needles are suitable for compacting the felt, while the fine needles are used for working in or performing detailed work on the felt motifs . All felting needles are suitable for use in the handles set for felting needles from the prym.ergonomics series. Each package contains 7 felting needles to be used as a filling or even a refill for the set.
