The Jococup is a stylish coffee cup made of glass with a silicone cap and sleeve. The glass is borosilicate glass, a strong glass that can withstand temperature differences better than ordinary glass and it can withstand both very high and low temperatures. Borosilicate glass is shock resistant and breaks less quickly, you can also count on your drink to retain its taste 100%. The lid is made of silicone and is equipped with a drinking hole. In the lid there is an extra air hole so that you do not drink vacuum. The lid is not leak-free but stays in place so you don't spill. The Jococup is equipped with a thermal sleeve made of silicone. This way, not only does your drink stay warm for a little longer, but the cup does not feel too hot from the outside so that you can grab it without any problems. The Jococup can be put in the microwave oven and dishwasher, is BPA-free and has the same model as a standard disposable coffee cup.
