This is a T-shirt that was released when BE:FIRST's single "Boom Boom Back" was released. I fell in love with the beautiful blue color and bought it, but it doesn't suit me at all, so I've never worn it... I have opened it, but it is an unused item. It is no longer sold. Size M. The back design is very cool. There are a few fold marks. Please understand. - Color: Acid Blue - Design: "BE:FIRST" logo and colorful design on the front - Design: Large "B" colorful design on the back Thank you for viewing.
