I was very satisfied with how our company information looked imprinted on the balloons. We blew them up at a local arts & fair show and gave them away to children.
The balloons seem to be made of strong rubber and we didn't have any to pop as we put helium in them. But we did have a problem tieing the balloons. The rubber was so 'thick', or something, that all 3 of us got blisters on the 2 fingers we wrapped the stem of the balloon around to make the knot!
