Tombow Dual Brush Pen Water-based Marker - N00 Colorless Blender

Tombow ABT Acid-Free Dual Brush Pen marker - N00 Colorless Blender.  Tested and working. Water-based marker with flexible brush tip end and firm fine tip end. Gently used once, so still in like-new condition and with full saturation. Both tips are still in original perfect form/shape.
Good for modern calligraphy; journaling; adult coloring books; graphic design; comics; and architectural, landscaping, industrial renderings and illustrations. Photos show the end types and blender marker test sample.
