Notes:

The ordinary type is flammable. For your and public safety, it is recommended to buy a flame-retardant type.

02、Sound-absorbing sponge has the problem of oxidation and discoloration. This has always been a common problem in the industry. Light-colored sponges are easily oxidized and yellowed. The lighter the color, the faster the yellowing speed. If you mind, take the light color carefully to avoid after-sales problems due to color problems. The discoloration problem is not a product quality problem.

03、Regarding the issue of chromatic aberration, due to factors such as chromatic aberration, light, temperature, personality, personal vision, and production process control, there are different feelings. If you are more sensitive to color, please buy with caution, thank you!
