The boys of VANNER lit up the night with the colorful spark of youth in their second batch of comeback teaser photos.

In this set of 'Sparkle' version images, the members completely shed the wild, dangerous mood portrayed in their 'Spark Start' images earlier this week, instead depicting a summer night of fun and healing. 

Meanwhile, VANNER's comeback with the release of their 3rd mini album 'Burn' and its title track "Automatic" is scheduled for September 30 at 6 PM KST.
