Optima Fixed Tip 18L Spear Point Shader Large. Renamed from the old 13SP tip. This new shader looks a lot like the #5 spear point but has squared off edges (not sharpened) and it is bent at a 45 degree angle for shading. Great for when you need to shade an area that's in a tight spot. Recommended in place of the old #13 pen for flat work pyrography. Available in smaller sizes 18M & 18S.
