1. Floor 20kg
Do you mean instead of 20kg
Floor => 20kg Flour (Mehl)? ^^

I had the same question, I didn't understand what is Floor

I was quite confused

I even left my confusion in the translation. Now with your suggestion, I think Flour is a logical word.
1. Floor 20kg (tôi không biết đây là gì
