My prostate hurt because of the saddle, but it's the best. So good

I bought it for a long distance, but as you can see in the picture, the spring part is covered by a hard plastic cover. Doesn't seem necessary, is the spring working properly because of the cover? I think it's better to just buy the basic type. It smells strongly of plastic.

Delivery is terribly fast Gaseongbin looks good, but the pain is okay
