Dr Guts has been busy in the lab experimenting with thicker, shinier silver pigments and NEW metal-tip applicators. Unfortunately, while his formula has reached new heights, we made one mistake: our mop mixing ball is too large! Our loss is your gain; for this first run of PROTOTYPES, we are discounting the markers from $9.99 to $5.99.

Beyond the mixing ball, we believe this is our best Dr Guts formula yet. The paint itself is ultra-shiny, super permanent, and has a perfect drip. Be among the first mad scientists to try it with this special offer! And don't forget: the Dr is counting on your feedback. Let us know what you think by emailing info@artprimo.com.

PLEASE NOTE: Because the mixing ball for this marker is slightly too large, it may become stuck in the head of the nib. This will cause a clogging effect. To keep your marker clog-free, either remove the mixing ball before use or shake the ball free and hold the marker horizontally as you write.
