The selection of plush toys is closely related to the quality of materials. There are many plush toys made of different materials in the market, and one common filler is PP cotton. However, compared to other materials, PP cotton has many unique characteristics and advantages.
　　First, let's compare the foam pellet wrapped with sponge with PP cotton. When using foam particles wrapped with sponge as filler, we will find that there is a clear sense of stratification when grasping, and the filler is unevenly distributed. Compared to it, PP cotton is more uniform during gripping, without a sense of layering, and the filler is also more evenly distributed.
　　In addition, there are also some differences between sponge wrapped tarpaulin and PP cotton. When grasping toys that use sponge wrapped with tarpaulin, we will feel uneven softness and hardness, and the rebound speed is too fast. In contrast, PP cotton has better softness and resilience during gripping.

　　In addition, there are also differences between Peng Jiaomian and PP cotton. Peng Jiaomian has a hard hand feel during gripping and is not easy to rebound. After gripping, there will be obvious pits, and the added materials will also be scattered unevenly. PP cotton, on the other hand, has better softness and resilience, making it more even in both hand feel and distribution.
　　More worrisome is that some plush toys use contaminated and harmful materials as additives. Although there may not be any obvious issues on the surface, when gripping, one may feel a lack of elasticity, poor softness, and due to the poor quality of the filling material, there may be situations where the washing becomes dirtier. Therefore, understanding the quality of additives is crucial for avoiding purchasing such low-quality products.
　　In addition to material quality, we can also evaluate the quality of plush toys from two aspects: color and design charm. Through observation, we can develop a sense of the overall shape of plush toys, which is the highest quality of toys - charm. Carefully designed and crafted plush toys give people a very cute and attractive feeling, while poorer products lack this feeling. The realization of this charm is not only related to realistic eyes, but also to the composition, placement, size ratio, and overall posture of various parts of the toy. This feeling is actually people's first impression.
　　In summary, selecting a good plush toy for processing is not only related to the selection of materials, but also includes observing the color and styling charm. In order to ensure the health and safety of children, we should pay attention to whether to use vacuum PP cotton when choosing plush toys, because the materials and plush of plush toys are items that children come into contact with for a long time. If the quality of the materials is poor, children may inhale them into the nose or mouth, causing allergies and other problems. Therefore, when choosing plush toys, choosing high-quality materials can provide children with a healthy and happy growth guarantee.
