To ensure a professional look, specify the finishing type, such as high-gloss piano lacquer, matte PU coating, or eco-friendly wax oil. The surface must be perfectly sanded (minimum 400 grit) to allow for clean laser engraving or the mounting of metal plates. If you require recessed areas for medals or plaques, confirm the CNC machining precision (tolerance within ±0.5mm). Additionally, check if the base includes anti-slip felt pads or EVA foam on the bottom to protect surfaces and provide stability.
