BLACK SEABREAM Sleeping Float Uses a new material PMI (high-density rigid foam), not ordinary foam. New material PMI rigid foam (high-density foam) Compared to conventional foam, it is hard and has no surface roughness, making it very smooth, so the surface coating adheres very well, resulting in a beautiful shine. In addition, conventional products had unstable quality and a lot of variation in buoyancy, but this PMI material is uniform, and the variation in buoyancy between products is also greatly reduced. ⚫︎ Hard material ⚫︎ High buoyancy ⚫︎ Does not absorb water Highly visible fluorescent yellow S-100 100mm ※ No price reduction
