Silicone‑based sewing lubricant formulated to reduce friction and thread breakage. Apply sparingly to thread so it glides smoothly through guides and tension discs, especially when using delicate metallic or rayon threads. Also helps needle penetration when sewing dense materials such as vinyl and leather and can be sparingly applied to the presser foot for smoother feeding. Keep capped when not in use and avoid overspill on fabrics.
