To be honest, we weren't initially a fan of the idea of German made bubbles. What have we come to when we resort to designer bubbles?! This being said, as far as bubble blowing is concerned, this is a primo experience. Pustefix make something that truly is better than the cheap two-dollar shop bubbles. The bubbles are vibrantly coloured with an almost metallic tint, and the liquid produces a huge amount of bubbles each time. We're convinced now!
