Where can I buy these Bisleri Vedica glass bottles?

A bit silly, but I really like these bottles. Got one of 5he bigger ones a year ago and still use it very often. Would like to replace it and also buy the small 300 ml ones. Only the crates are available on the website, just wanted to buy a few. https://www.bisleri.com/product-detail/bisleri-vedica-300-ml-glass-water-bottle?city_id=79
