Makes sense that Tale of Painters would review them.
From the review:
Last Saturday Games Workshop released a set of six new technical paints for various effects like blood, corrosion or slime. We at Tale of Painters got all of them and gave them a try on an innocent skeleton warrior.
Head over to Tale of Painters for both a review of the new technical paints as well as for an tutorial for painting a gritty and dirty skeleton warrior.
