VersaColor is a fade-resistant pigment ink which is available in a huge variety of colours. This pad is in the Polar Blue colourway.
It dries reasonably slowly, making it ideal for embossing. However it's not suitable for use on non-porous surfaces (such as glossy card, acetate or vellum) unless heat embossed.
The inkpads are perfect for the direct-to-paper technique, or you can use a wet paintbrush or waterbrush to draw colour into an image. And they're easy to clean after use.
