High-quality double-ended blending pens for smooth, controlled sketching and finishing. Key features Materials: Black tip made of soft sponge, white tip made of felt, body made of durable ABS plastic. Tips blend smoothly without damaging paper. Double-headed design: Each pen has two different tips for flexible use — larger tips for broad transitions and midtone blending, smaller tips for detailing and tight edges. Set: 14 sponge pens included, in two sizes to cover most artistic needs and keep spares on hand. Durable and reusable: Soft sponge tip resists peeling and holds up to repeated use; ABS barrel is comfortable to hold and built for long service life. Paper-safe: Gentle tips allow blending without tearing or roughening the surface. Sizes and dimensions Larger pen: tip diameter ~0.47 inches, total length ~5.94 inches. Black sponge tip is ideal for shadow-side transitions; larger white felt tip blends midtones into shadows or bright areas. Smaller pen: tip diameter ~0.24 inches, total length ~5.51 inches. Black sponge tip is suited for preliminary blending and shadow details; smaller white felt tip handles fine-detail blending. How this product helps you Faster, cleaner blends: Replace fingertip smudging or bulky tortillons with precise sponge and felt tips that produce consistent gradients and softer transitions. Better control across scales: Two tip sizes let you jump from broad area blending to intricate details without changing tools. Always ready: A 14-piece supply ensures you have fresh tips available and reduces the need to clean tools during work sessions. Compatibility and performance Works well with graphite, charcoal, pastel, pencil, conté and other dry media for blending and softening edges. Soft sponge and felt tips adapt to paper texture while minimizing abrasion or tearing. Built for steady performance and repeated use when used appropriately with dry media. Practical use scenarios Portrait drawing: Use the larger black sponge tip to smooth shadow transitions on cheeks and neck, then refine facial details with the smaller white felt tip. Sketch classes and study work: Keep several pens on hand to quickly blend midtones and shadows across different sheets without downtime for cleaning. Mixed-media sketches: Soften pencil lines, blend charcoal edges, and integrate pastel areas cleanly to produce balanced, professional-looking studies. What you get 14 double-ended sponge pens (mix of two sizes) with black sponge tips and white felt tips, housed in sturdy ABS barrels for comfortable handling and long-term use.
