Coloring Materials - Grey Brush Pens

My husband @deveerei bought these pens recently and they're really fun to use. I used them to color up the "Gorilla Mouse" drawing I've posted recently.

It's a set of 6 pens with different shades of grey. It costs 299 Philippine pesos or roughly 6 USD.

The case looks great especially with the free lace it has which looks like braided rope and faux leather.
