Stainless steel handle with medical grade nylon bristle. The 3/8" brush fits both the 9mm and 12mm straws.
GlassDharma was started by David Leonhardt, a lampworker (glassblower) with over 10 years experience. While doing some work for a local glass shop in town he noticed that the owner had glass drinking straws for sale and was intrigued. He immediately recognized that here was a partial solution to our â€œplastics problemâ€.
Now, granted, there are a lot more plastics in our world than just drinking straws, but based on his research, McDonald's alone uses about 50 million straws EACH day. That's just from one fast food restaurant, on one day. Expand that to all other restaurants - that's a lot of straws and a lot of plastic. His goal is to get 2% of the US population to switch to glass straws - that's about 6 million people which adds up to a mountain of plastic removed from our waste stream.
