Posca Markers (affiliate link) are a great way to create bold and colourful lines that stand out, without having to worry about mess or waste. They work on almost any surface, so artists can make use of them in a variety of applications and settings. However, while Posca markers are incredibly versatile, they require significant amounts of energy to produce. This article will assess the environmental sustainability of these markers across their life cycle, from raw material acquisition and manufacturing to transportation and use/re-use/maintenance.

Versatility Across Various Surfaces

Developed in 1983 by Japanese company Uni Mitsubishi Pencil, Posca marker are real paint markers that are water-based. They contain binders, which hold the pigment together, and are created from organic or synthetic materials. The binders used in Posca markers are most likely synthetic polymers. These are made from a mix of resins, such as polyethylene or polyester, and cellulose. These are then mixed with water to form a gel that sets once the liquid evaporates. The binders are then added to the paint, along with a variety of additives such as whitening agents and stabiliser.

Posca marker pens have a range of different tip styles that allow for a diverse array of creative possibilities, from fine line detail to broad swooping strokes. There are also several replaceable/reversible tips available, so if your tip is damaged, you don’t have to throw away the entire marker! The pens have a wide colour selection and can be used on almost any surface, including paper, cardboard, wood and glass. To ensure a permanent finish on sanded or rough surfaces, you can fix your designs with two coats of water-based varnish.
