Innovative dualtip blending pens designed for precise, controlled shading and seamless transitions Key benefits Versatile blending options: Dual tips let you switch between broad shadow blending and fine detail work without changing tools. Improved control and finish: Use the larger black sponge tip for smooth shadowside transitions and the larger white felt tip to blend halftones into light and dark areas for more natural gradients. The smaller black sponge tip handles fine details and tight areas. Saves time and supplies: Two sizes in one set cover a range of drawing needs so you don't need multiple singlepurpose tools. Durable and reusable: Washable plastic poles and resilient tips extend tool life for repeated use in projects or classroom settings. What's included Four blending sponge pens in two sizes (combination suitable for multiple drawing needs). Note: the white felt tip may contain black wool; this does not affect performance or blending ability. Specifications Larger pen: nib diameter approx. 0.47 inch / 1.2 cm; total length 5.9 inch / 15 cm Smaller pen: nib diameter approx. 0.24 inch / 0.6 cm; total length 5.51 inch / 14 cm Tip materials: black tip made of sponge, white tip made of felt Pole material: robust plastic for better grip; washable and reusable Materials and performance Sponge and felt tips provide smooth, consistent blending across tonal ranges. Plastic pole is lightweight, comfortable to hold and simple to clean. Designed to produce clean transitions between dark, midtone, and light areas without smudging details. Practical use scenarios Sketching and shading: Quickly soften charcoal or graphite shadows and create natural midtone transitions with the larger tips while preserving detail with the smaller black tip. Art class and workshop use: A durable, reusable set that supplies enough tools for small group exercises and repeated practice. Detail refinement: Use the smaller black sponge tip to blend tight edges, hair, fabric folds, or small facial features without losing sharpness. Care and compatibility Washable plastic poles and resilient tips make the pens suitable for repeated use. Compatible with typical sketching media that benefit from smudging and tonal blending (charcoal, graphite, and similar dry media). Store tips upright or capped when not in use to prolong life. Practical, reliable, and built for artists who need controlled blending and consistent results across a range of sketching tasks.
