Stop disposable - Go reusable! Our Challenge Cup with calibration mark 500ml is made of renewable raw materials (from the remains of the pressed sugar cane plant) and therefore impresses with its very good CO2 balance. Whether for soccer stadiums, open-air concerts or festivals - our sustainable unbreakable BIO alternative should be there in any case. The cup can be easily cleaned in the industrial dishwasher for reuse at the next event (min. 500 cycles). Our Challenge Cup is 100% recyclable and "Made in Germany".
