In the context of the pursuit of a higher quality of life, a product that can really solve the problem is particularly important. The second generation of Qicai shell is such an innovative work. It redefines the protection standard with the design concept of "increasing and thickening.

the research and development team of the odd color shell is well aware of the user's pain points and has made deep improvements on the basis of the first generation of products. The new enlarged size covers a wider range and effectively prevents edge spillage, while the significantly thickened material further enhances sealing and durability. This combination not only makes daily use more reliable, but also extends the life of the product.

as to why such a special design scheme was chosen, the R & D personnel explained: "the traditional shell often causes the elasticity to decrease or even damage after long-term use due to insufficient thickness, resulting in leakage." Therefore, they decided to choose a new type of composite material as the main frame support layer, and at the same time increase the density of the surface coating to form a double barrier system to ensure that the liquid cannot easily penetrate the shell into the inner cavity to harm the equipment itself or cause environmental pollution.

Of course, theoretical perfection needs to stand the test of practice. For this reason, the government organized a series of severe test projects, including but not limited to immersion test (lasting for more than 72 hours), high-pressure jet flushing and repeated folding and stretching, etc. No signs of leakage were found, which is enough to prove that the model does have super pressure resistance and stable performance.

In addition to technological innovation, human consideration is also an indispensable part. For example, the exclusive cutting style is customized for different models to ensure tight fitting without leaving gaps and not excessively tight affecting the operating feel. In addition, a detachable hook and loop strap is attached to facilitate fixing the position to avoid the risk of accidental falling off and loss.

since its listing, it has received a lot of favorable comments. among them, many consumers have left messages saying that they were always worried that ordinary plastic bags would not be strong enough to break down. now they have finally found an ideal substitute. they are very satisfied and strongly recommend the convenience brought by scientific and technological progress to their friends.
