Lightstick official Red Velvet
The name of the lightstick is Kim Mam Bong, an abbreviation for dumpling or cupcake, since it has this shape. It comes in pearl and pastel coral, with a delicate and very feminine design.
When inverted, it forms the number 5 referring to the number of members of the group and by joining it with another lightstick, they form the Reveluv logo.
Furthermore this represents the group's love for all fans like you, who have been a huge source of support and energy for them. Therefore, the singers are considered as a whole with their fandom.
