Dove Blender Pen (http://store.scrapbook.com/dovblenrefpe.html) is a must tool for me. So I bought this refill (http://store.scrapbook.com/dovblenref.html) and replacement tips.
This pen can easy to get the fabulous effect for coloring images with crayons (polychromos pencils is also available) , watercolor pencils, chalks ,etc. .
Chalk square dose not need to be sprayed to be permanent.
And this is so useful for picking up color from an ink pad.
This blender pen is so useful, and need to the stock of this replacement tips for me.
Since I just got this pen, I haven't had to change out the tips. But so glad I bought the three items.
Actually, I didn't have to "buy" them cause I won a challenge here on sb.com being a $10 gift certificate and that covered the cost.
