32 oz Modern Round Bottle We have been asked for these for years at shows. This high density polyethylene bottle meets FDA standards.These are 32 oz heavy duty plastic bottles that can be used with both types of our pop bottle founts but it must be used with a spring and not the nylon strap that comes with the screw on. Translucent so you can see the water level. Also have the 16 oz available. Picture shown with blue liquid to show bottle shape. We recomend springs for this size bottle to hold the bottle on to cage.
