The brown monster, also known as the leather marble, could gain weight in the bygone days of football. Getting the brown leather ball wrong on the head hurt, especially when the monster had soaked up rainwater like a sponge or had been lying in the ditch after a drop. If you got the very heavy marble brushed against your thigh, then such a thigh-beater left an imprint. FC Kluif brings this brown retro ball back into play, but now without monstrous features.

The ball has a retro design. The FC Kluif logo, together with the year of foundation, can be found on the ball in golden color. Together with the 'What's life without goals' and 'Football Fanatics' lyrics, the ball screams football! In combination with the brown color, this creates a retro look. In addition, the ball can simply be used for a good game of 'old-fashioned' football! The inner ball is made of rubber. The ball is stitched by hand. 100% PVC - leather look, rubber bladder and hand stitched.
