Kids love BLOpens as they can easily create fantastic pictures with amazing airbrush effects! The BLOpens Animal Set includes 6 great stencils to create some wonderful, colourful animal themed pictures. Just place a stencil on a piece of paper, blow into the pen and see your picture appear! Try blowing in lines and circles, harder or softer for different results. You can also use the same pens for drawing extra details to give your design a perfect finishing touch!
