• GUARANTEED against failure when pouring Hot Coffee, Tea, etc. - - - If they break - we replace them. We make them ultra-strong, but of course caution should always be used when pouring hot liquids into glass or ceramic. We'll replace a thermal fracture during the first year of use.
• HercuGlass Treated to be Ultra-Break Resistant
• Strengthened by the same process as aircraft windshields
• Comes with Plastic Covers - Keeps bugs and sand out of your moonshine and soda
• Can be used as Travel Mug.

By customer request we now offer the "Mason" and County Fair mugs with the included plastic screw-on caps. You can use these caps to convert your plain old jar into a TRAVEL or outdoor mug. No more bugs or sand in the moonshine!! Great for picnics, campers, back yard barbeques, etc.
