Another great quality product made by Evolution Glass. it's about 16 inch tall, great quality double double wheel percolator and comes with 14mm 4 pinch herb bowl. Evolution Glass is the next premier glass blowing team. Companies with this much talent coming together in one place only come around once every decade, and the work they produce will last for generations. Coming out of the PNW, Evolution Glass is going to take over the glass industry with unmatched quality and innovation. The secret lies in their super-thick simax glass tubing and joints in combination with artistic style and color that is second to none.
