Founded in 2009, Perth registered the Perth trademark in 2013 to specialize in water-filled hot water bags, and in 2015 it was rejected due to the overlap of the trademark with the name of an Australian city, so a new trademark Borth was launched, and the product is consistent with Perth.
 
Borth warm water bag is a cost-effective route, the price is between 50 ~ 80 yuan, mainly divided into four categories: hand warming, shoulder and neck warming, waist and abdomen and foot warming, the material is mainly PVC, and silicone is also involved. Borth products have passed TUV, CE, SGS certification, which is relatively rare among domestic brands, and the product safety is high.
 
The baby warm water bag is the treasure of Borth's town store, and the emergence of its A026 warm water bag fills the gap in the baby warm water bag market. Babies are prone to inhale more air after breastfeeding, and due to the imperfect development of the intestines, it is easy to cause intestinal colic, and the incessant crying often makes parents helpless. A026 is designed with a fixed waist belt, which can fix the warm water bag on the baby's abdomen, and the heat transfer is more sufficient, so as to achieve the effect of relieving intestinal colic. In addition, the A026 belt is made of 3 layers of pure cotton, which is of moderate thickness and can also avoid low-temperature burns.
 
For people who sit in the office for a long time, cervical spine problems have become a pain to carry around, and Borth U200 is a product designed for the shoulder and neck, similar to U-shaped boxing gloves. Different from other brands of U-shaped warm water bags, the U200 has designed buttons for the warm water bags, which can make the "U-shaped" become "O-shaped", which fits the neck better and warms the neck better. However, U200 still has not been able to solve the common problem of U-shaped warm water bags, and the overweight bag will bring discomfort to the cervical spine, so it is recommended not to use it for more than 30 minutes each time.
 
The Borth silicone hot water bag G520 is similar to the Pocatan, the difference is that the Borth hot water bag is more slender, and the volume of 0.52L is only half that of the Pocatan. The G520 also has a sparse large heart pattern on the front of the hot water bag body, and a fine heart-shaped pattern on the reverse side, providing two temperature options. Its heat insulation jacket and warm water bag also add heart-shaped elements, echoing each other, the price of 79 yuan is relatively close to the people.
 
Borth's hot water bag is basically odorless, provides a 2-year warranty, and is more convenient for online shopping, and is currently only available on JD.com.
