These are my "go to" pencils for card making. I have been using watercolor pencils for nearly six years. These pencils work well on watercolor paper and card stock. When using card stock I use a blender pen to soften the color if desired.The first set I bought was by General. I bought the watercolor kit which includes instructions, a pencil sharpener and printed designs for practice. If I remember correctly there are between 24 and 36 pencils in the set and well worth the money. I still have most of these pencils and I rely on them when I want a to be sure the color on the pencil barrel is the same as the lead. These sharpen easily, but more importantly the lead does not break when being sharpened.I recommend this set of pencils if you are new to water coloring and don't want to purchase the more expensive brands or you just want a quality set of water color pencils.
