Can you still remember the time of the broken thermos flask spilling out of your purse or new favorite backpack? Fortunately, these times are over with the multi-insulated stainless steel thermos flasks, bottles and cups of today. BUT there are, in addition to the gradations in the design claim, which is known to be in the eye of the beholder, quite qualitative differences, which should be considered when buying a thermo-insulated bottle. For example, they can be insulated 2 or 3 times, have differences in the degree of hardness of the steel used and the paint finish, or have ergonomic features. The Corkcycle thermos and thermos cups, also called tumblers, not only give you a choice of different sizes and capacities, but you can also look forward to a high quality reusable tableware. Both Corkcicle bottles and tumblers are triple insulated and made from high quality 18/8 steel, keeping your drinks hot for 12h and cool for 25h. In addition to the scratch-resistant paint, the ergonomic handle shape and the anti-slip flooring, the bottles are also characterized by an extra wide opening for ice cubes and co, so that in everyday use just fun and frustration, as formerly fortunately belong to the past. By daily use of these practical and environmentally friendly reusable water bottles and cups you also contribute actively to plastic avoidance and waste reduction. In addition, 5% of Corkcicle's total revenue goes to social water projects as, unfortunately, clean drinking water is still a privilege for only part of humanity on this wonderful and actually blue planet.
