Review on Sparkling Solutions: Borosilicate Glass Tubing Cleaning Brushes by Jeff Drollinger

Arrived with no cracks, chips or scratches as described by the seller. Fairly well packaged, mostly in the bubble wrap that came in the box that came in the padded envelope. If you're planning on using them as a chillum, they're big, small and skinny (discreet) but with a head that's a bit larger than your average striker and just the right diameter to fit a roach so you can can finish. without getting burned. Pipe cleaners are a great little bonus. Incidentally, they bulge slightly at the collar. In general I am very satisfied.
