PAVINA® OUTDOOR is a crystal clear lightweight double wall tumbler designed for the outdoors. Ideal for everyday use and functional for large outdoor barbeques. We have recently invented a new technique for the production of our double wall tumblers by using shatterproof plastic. The tumblers are produced in one whole piece - no welding and no possibility of leaking and even better than that, it is all done in a sustainable way. Product features and benefits: Ideal for serving your favourite outdoors and poolside drinks; Glasses maintain their clarity even through regular use; In the end you can simply put them in the dishwasher; Five different sizes available for your favourite drink.
