The 127HS already is a classic amongst pump-markers - equipped with an easily exchangeable 2mm fine-tip (downgradable to 1mm) and available in 50 brilliant colors.
The 127HS-EF is a perfect outliner. It is equipped with an extra-fine 1mm tip, that can be exchanged with the 2mm fine-tip at any time - available in black and white.
A special technical gimmick is the patented capillary system that guarantees an even and controlled dye distribution. Together with the Flowmaster(TM) pump-valve, that provides a controlled paint-flow, these markers show the best writing performance on almost every surface. The mixing balls inside the markers make sure that the highly concentrated pigments are evenly distributed within the paint for optimal writing results. Therefore it is recommended to shake your marker well before use. Both markers are refillable - ONE4ALL(TM) refills are available in 34 colors and two sizes: as 180ml and as 30ml bottle.
The highly pigmented, acrylic-based hybrid-paint is easily mixable with other ONE4ALL(TM) colors (for individual shading), it can be diluted with water (for translucent effects) or with acetone (for permanency on fatty surfaces). It works on almost every surface, is silk-matt, quick-drying, has an incredible opacity and is absolutely UV-resistant.
Both markers have perfect sketching characteristics.
