The magical Quick-Milk straw (Tryllemælkssugerør) is our, by far, best-selling and most popular product over the last 8-10 years – children love them and just can´t get enough of them.The ‘Tryllemælk’ straw is being placed in a glass of milk and then the magic starts: the milk stays the same in the glass but the taste and colour changes in a magic way.
