Summer is drawing to a close, but the parties never end! For a cool party you need a great atmosphere, decorations and of course cocktails! For the preparation of cool cocktails there is a cool, stylish circular infusion vessel called Porthole by Martin Kastner. The vessels are handcrafted and used to create, display, and serve a variety of time-lapse infusions for seasonal cocktails. You can also use it on oils, teas, and many other things. The porthole holds 390 ml of liquid and is made of precision-cut, tempered glass with low iron content, food-grade Delrin, and stainless steel. Each porthole is supplied with three photo-etched stainless steel filter screens of different densities and a flexible silicone cap. This is one of the most stylish accessories you can ever use at a party!
