The washable and colorful shell grabs his well. The balloon is still full, even though he's already blown for 1 week. Since I have no air pump, I've blown him normal, so that works too, but is not recommended in the package insert. A second balloon is equally thereby. Friends of ours have sewn myself an envelope for balloons, in view of the work that's I think justify the price. We have a lot of fun with it and I want to have more colors!
