Earlier this week I treated myself to this pack of marker pens. They are double ended pens - one end is a bullet point and the other is a traditional wedge shape. I picked them up from The Works for just £15.00 and have been having great fun experimenting with different effects.
Some of the colours are a bit too bright for my taste but the coverage is very good - although they do 'bleed-through' on thinner paper.
Many years ago I had a similar set of brush pens which were also double ended and I produced a number of coloured sketches using them.
I'm sure I will have more to post as the month goes on.
