There is a multitude of uses for needle files in all crafts.
Having an assortment of shapes and sizes so this set has 6 different shapes for any nook and corner that needs smoothing and shaping. Each has a super fine tooth.
Each is 6.5" long and no more than 3/8" wide.
My recommendation is to slip off the red rubber handle cover and construct a polymer clay handle on it so you have a grip that will fit your hand.
