Holbein Meltz Colored Pencil Blender Pen is a transparent liquid blender marker designed for creating smooth color transitions and subtle brush-like effects with Holbein Artists Colored Pencils. This double-ended pen features both round and brush felt tips, allowing for versatile blending techniques. Apply the pen over pencils that have been layered or applied in a cross-hatched pattern to achieve seamless blending and watercolor-like effects.

The Meltz Blender Pen works well with oil-based pencils to create effortless gradations and a brushed appearance. However, it may not blend metallic colors or soft white effectively and might not be compatible with other pencil brands. It may also stain the opposite side of the paper depending on its type and thickness, so testing on your surface is recommended. For the best results, clean the pen tip between colors to maintain clarity and brightness.
