collaborated with a stationery brand to customize hardware bases for office pen holders. Using 304 stainless steel material, through precision turning and polishing processes, the base thickness is 5mm, with moderate weight, which can effectively prevent the pen holder from tipping over, suitable for various pen holder shapes such as round and square. The anti-slip pattern design on the surface increases friction, fits the desktop without sliding, and the edges are polished smooth without burrs, which does not scratch the desktop. The size can be customized according to needs, adapting to pen holders of different heights and diameters. The surface is mirror polished with high gloss, rust-proof and easy to clean, helping the partner increase pen holder sales by 40% and becoming an essential supporting product for office desktops
