DHS Ma Long 3 Blade Authenticity Card - Translation Needed

[dfreeman012]

Hi everyone,

I recently bought a new DHS Ma Long 3 Blade and it came with an authenticity card and there are a couple of the items that I can guess what they are. I was hoping that someone would be able to translate teh writing on this for me. I am especially wondering what is the line next to "61%".

Thanks for your help.

Dave
