The original "Indo-Skeleton" Functional Support & Retention System // 9.5 – 12 Purple/Sail/Rainbow Era Boxes
FIG. 1: 3D RENDER
The FSR-MK.I Indo-Skeleton is a sneaker box reinforcement system designed to prevent crushing, collapse, and long-term structural degradation of Nike SB shoe boxes. Built using a hybrid PLA and TPU lattice structure, it distributes vertical load across internal support points, enabling safe stacking of heavy sneaker collections.
Ideal for collectors searching for: sneaker box protector, stackable sneaker storage solution, Nike SB box support, how to prevent sneaker box damage, and heavy-duty shoe box reinforcement systems.
Tested against sustained loads exceeding 200 lbs, the FSR-MK.I allows collectors to safely stack multiple boxes without compromising structural integrity.
