It is worth mentioning Libby's Rooster Cup, which is a glass that has been a hot mess on the social networking site Instagram, the shape is a variant of the famous Mason Cup, with a handle, the reason why it is called a Rooster Cup, is because there is a rooster on this cup of Libby, after it spread, whether it is a Libby brand or not, this shape of the cup is called a Rooster Cup. The rooster cup is also the most sold style in the RLB Tmall store, reaching more than 200,000 sales, and other brands have not been counted, which shows the popularity of the rooster cup.

In addition to the particularly popular rooster cups, RLB also covers a wide range of popular beverage cups, whether it is an individual who opens a cold drink shop or pursues a fashionable style, in order to gain brand protection at the same time, RLB's beverage glasses are a good choice.

However, RLB glasses are more suitable for cold drinks, although there are some heat-resistant glasses, but they do not use high-silicate boron glass with better heat resistance, so it is not recommended to use them as hot drink cups for safety reasons.
