Below we share the best tips to choose for Rock Painting. The very high quality  materials used guarantees a stroke that is always perfectly smooth. Take this into consideration and they make for easy use on a rock, however the rock has so many variables – porosity, bumps, angles etc. The pens do have a few quirks to understand as they are PAINT pens not COLOUR IN felt tip pens. We share the know how below.

Here are some tips sizes to choose for Rock Painting.
1. 3m size is the most versitile size to place colour on your rock. It is small enough to get in tight corners as well as providing great coverage to large areas.
2. In Black & White at the very least grab a 1m or a 1mr. These will be for outlining and highlights. Once you get used to using them, you will probably grab the whole colour range like us.
3. If you have extra large areas the 5m size is perfect to colour in .

Posca Pens have a unique valve mechanism that guarantees a perfect seal for the marker.

Helps conserve the paint to not dry out.

The same mechanism is used to prime the POSCA for use.

Helps to saturate the tip as often as necessary during creation.

Stops water from back flushing in to the barrel during nib cleaning.

WATER SOLUBLE – POSCA paint is “water-soluble” It can be diluted to produce a gradient effect and they produce awesome shading effects on rocks.MIXABLE – As long as the paint is wet, colours can be mixed. If the tip is stained, just clean it and re-prime the marker to restore the initial colour.
