Unique Design - It can be one or four - It's designed to help you carry four different glasses of beer at once. When pushed together they look to form one large pint glass, but they come apart like pieces of a pie to form 4 different drinking glasses. Sturdy and Durable - Made of clear thick acrylic our pub glasses are durable, they wont chip or break very easily and will keep your beer cold. You can confidently rest these glasses on any surface without worrying. Incorporated Vertical Grooves - The clever new design incorporated vertical grooves, which slot in to one another when held together, preventing the glasses from slipping around in your hands. They are also narrower towards the middle, which makes it easier for you to get a good grip of them. Usage - You can carry it like you would 1 pint glass with either one hand around the entire bottom, or use both hands around the entire perimeter of the glasses. They then easily come apart once you set them down. Great Gift - There is no doubt that this is one of the most special wine glasses this year. Perfect gift to your friends or family members who love to drink.
