The pump is solid red and does exactly what it should do, namely pump air into the balloon. She is especially effective; during my previous pumps a way to breathe needed in order to then blow on the way back in the air balloon can, this pump pumps both in one direction and in the other direction the air in the balloon. As soon as I had my modeling balloons never inflated, you have to watch almost that they still retain their small safety tip.
From me an unrestricted Purchase Recommendation! Have fun model!
