There are different things that gets my attention when I browse old razor and blade advertisements. Sometimes it is an interesting picture. Sometimes it is a razor that is unknown to me. Sometimes it is hilarious claims in the text.
And sometimes… it is the bright colour.

Now, I don’t read Chinese.. but at least Google Translate gives an idea of what it says.
“Convenient, safe, and comfortable.”
“Available in all major department stores.”
And… “Geely security is difficult.”? I think Google messed that one up.
But the ad is bright and cheerful, so there you go.
