I have been using Castle Arts supplies for quite some time now, I just love the finish all of their products give. The glitter gel pens are just amazing, & the brush pens, I use your paints, pencils in the black case, great for travel, your sketch pencils are the best I have ever used. In fact I am a forever customer because I would struggle to get such excellent products & fantastic customer services & deliveries. Just great from start to finish.
