My sister gave this set of blowpens to the boys a few days ago. I could not find any of the bond papers we have around here (because everything's not in their proper place due to the ongoing renovations) so I gave them 2 folders to use for their creations. Ethan was very excited. Nikki had some difficulty blowing but at least he kept on trying. Because they enjoyed the activity a lot, they used up all the pens! But no worries because I bought them another set and it only cost P30! Another great thing? It's washable. =D
