From the first generation to the second generation: the evolutionary history of the coli bottle
Since its inception, KELI bottles have always been committed to the development of better and more innovative glass products. From the initial single model to today's diversified series, each iteration is to provide users with a better experience. Especially after the launch of the second-generation Coli bottle, we have introduced many humanized new features on the basis of retaining the classic design. For example, the function of heat preservation and cold preservation is added to make the water temperature more lasting and stable; the curve of the bottle body is optimized to make it more comfortable to hold; most importantly, the design of super capacity is realized, which fully meets the water demand of users in different scenes.

Why choose stainless steel?
Among the many available materials, we have chosen stainless steel as the main raw material for production. This is because stainless steel has excellent corrosion resistance and abrasion resistance, and it can maintain a bright and clean appearance even after long-term use. More importantly, it is non-toxic and harmless, does not release any harmful substances, and is safe and reliable. In contrast, plastic products are prone to aging and deterioration, and glass is too fragile and fragile to achieve the advantages of stainless steel. Therefore, the choice of stainless steel is not only for environmental protection, but also to protect the health rights of every user.
Large capacity design: to meet all-weather water replenishment needs
Considering the modern fast-paced lifestyle, people often do not have enough time to replenish water frequently. To this end, the second generation of the bottle is specially designed with a large capacity of up to 750ml, which is almost equivalent to the total amount of two bottles of standard mineral water. This means that whether it is the first glass of water in the morning, the work gap at noon, the tea time in the afternoon, or even the way home in the evening, you can easily cope with the multiple drinking needs of the day with only one filling. Moreover, the large opening design is convenient for cleaning, ensuring clean and hygienic use every time.

Portable and innovative: the unique charm of the second-generation Cori bottle
In addition to excellent functionality, the second-generation Cori bottle is also outstanding in appearance design. It uses ergonomic principles to create an arc that conforms to the palm grip, even if it is held for a long time without fatigue. In addition, the bottle mouth is equipped with a special leak-proof sealing ring, even if inverted, there will be no liquid leakage phenomenon, very suitable for carrying travel. What's more interesting is that we have also configured a cute silicone sleeve for each bottle, which can not only play a buffering and protecting role, but also increase friction and prevent slipping.
The perfect partner for multiple scenarios
Whether in the school classroom, the rest area of the office, the training ground of the gym, or the outdoor hiking adventure, the second-generation Cori bottle can become your most effective helper. Its versatility and adaptability make it an ideal choice for people of all ages. For students, it can be a friend who accompanies them through a long time of self-study; for white-collar workers in the workplace, it is a sharp weapon that can be refreshed at any time; and for people who love sports, this water cup is a necessary companion.

Personalized Customization Service: Create Your Unique
To give each user a unique product experience, we have introduced personalized customization services.
