[FOR THE SMOOTHEST TASTIEST SHOTS: The original double bubble shot glass that allows you to serve bomb shots in style. Patented layered shape allows you to serve the shot and chaser in 1 glass so the last thing you taste is the chaser. 2.25 oz on the bottom 1.25 oz on top. No magic or witchcraft involved: just the simple laws of physics we all learned in school. Liquor is less dense than most chasers so the liquids naturally want to separate. FUN! & UNIQUE - One of a kind presentation & visual experience! Clear for visibility of contents and to coordinate with most tableware drinkware and decorations. Great for Bars Restaurants Catering Events Night Clubs and Bachelor or Bachelorette Parties! PREMIUM DURABLE PLASTIC - Crafted from premium quality & thick plastic Quaffer glasses won’t break easily. Ideal for heavy duty use in bars tailgating restaurants and other commercial setups. CONVERSATION STARTER – Be a bartending magician! Step up your party game and wow all your friends. BEACH FRIENDLY – Perfect for locations where glass is not ideal or permitted but you still want to Quaffer like a champion. HOW TO QUAFFER: To set up your shot simply pour in the chaser first and then pour alcohol on top against the inside of the glass (not directly into the bottom chamber). Every shot you drink will be more palatable because you will immediately taste the chaser following the alcohol so no more cringing. Recommended to wash with hand by soap and water. Exposure to excessive heat may warp the shape like a melty face. [Risk Free Guarantee] We stand with pride behind our brand and products.
