Let me, an insider, tell you: There are several signs of the binary star, among which, like two birds, we often see them, and they are also the same signs as the store doors we see! And F-MAN is an English symbol, which means celebrity! Behind the binary star is a star, which is a sign. You will probably see it on your shoes! The other is DBSD, which is the abbreviation of binary star!

These are all true, which is the difference between Double Star and other brands!

Generally speaking, the logo of two birds and F-MAN are well-known, while others are not well-known. In order to make it clear to consumers at a glance, we improved it in 2009, and then people will rarely see the logo of DBSD in the market! Please feel free to buy!
