Sipa Tyre markers use oil-based ink to mark on any surface including our rubber Ninja glove material.
If your glove is UV faded to a lighter colour or darkened from pool chemicals you can quickly lighten or darken the colour by marking colour on the glove.
We recommend putting colour in the valleys of the glove so it adjusts the tone of the glove and can't be rubbed off with friction. Colour on contact areas will eventually rub off high-contact areas like knuckles.
