This is a Purist bottle printed for us by Specialized Water Bottles in Morgan Hill California. Bidons not bottles worked with us on this bottle making this Bidon #004 which is labeled on the back. The bottle is infused with silicon dioxide, which forms a protective barrier inside the bottle to prevent odors, stains and mold from attaching to the inner surface. The bottle holds 22 fluid ounces and has a black MoFlo screw on top. The bottle is recyclable when it has reached the end of its life.
