With the exception of the 327HS and 427HS, all ONE4ALL markers are equipped with the patented capillary system, which enables a constant paint distribution. Moreover, it makes a long-lasting tip exchange possible. ONE4ALL markers are built to refill and no disposable product. Next to high-value applications and artworks (mixed media) the ONE4ALL acrylic color system is ideal for the design of ornamental items on nearly all surfaces. Quality restrictions and a loss of color characteristics might appear when using unclean or wrongly prepared surfaces. Generally a previous check of the color on the chosen surface at a discreet place is advisable. Please note that absorbent, flexible and uneven surfaces are naturally more unsuitable for paintings than smooth and unabsorbent surfaces.Details:Fluorescent pink2 mm tip sizeAcrylic paintPatented capillary system for constant paint distributionEasy tip exchangeFlowmaster™ valve for active paint flow controlRefillableFor use on nearly all surfaces
