collaborated with a bathroom daily necessities brand to customize hardware brackets for household toothbrush holders. Using 304 stainless steel material, through precision CNC cutting and grinding processes, the bracket thickness is 1.5mm, with a stable structure, which can place 2-4 toothbrushes at the same time. The anti-slip base design prevents the bracket from tipping over, suitable for the humid environment of the bathroom. The toothbrush card slots are uniform in size, which can firmly fix the toothbrush and not easy to slip. The surface is mirror polished, rust-proof, easy to clean, and not easy to breed bacteria. Single-layer and double-layer structures can be customized according to needs. This customized bracket helped the partner increase toothbrush holder sales by 43% and received wide praise from consumers.
