Query: Great!

These bubbles were great. They worked very well and our dog had a blast with them. A little messy though. They are much thicker than normal bubbles and are sticky. We had to wipe our dog down afterwards because they were caked in this coat, kind of gluey. But it was worth it cause he had a blast with them and they produced great bubbles.
