Its products have passed the BS and SGS certification required for export to Europe and the United States, and the quality is more guaranteed.
 
Sanpu's warm water bag mainly takes the cost-effective route, the price of ordinary styles is between 20~40 yuan, and the special styles are between 40~70 yuan. Its warm water bag has a fashionable design style, which is divided into two series: PVC and silicone that can be directly microwaved, of which PVC series is the main product of Sanpu.
 
Different from other brands, the biggest highlight of Sanpu PVC warm water bag is its unified transparent color design, which is not only beautiful, but also can control the amount of water more intuitively when filling water to avoid scalding. And its PVC thickness reaches 2.4mm (the thickness of the old dime), which is 0.1mm thicker than Hugo Frosch, and the bag body will not overheat, and the heat preservation effect is better, so the elderly can also use it with confidence. However, the Sanpu PVC warm water bag also smells slightly, but fortunately, it will gradually dissipate after use.

The silicone warm water bag is similar to the Bosil workmanship, but the price is about 10 yuan cheaper, the main difference is that the workmanship of the thermal insulation cover of Sanpu is general and does not come with gift packaging.
