GaoLeshi custom foam inserts are die-cut or CNC-cut to hold a product precisely inside its box – gift packaging, electronics, instruments, tools and fragile goods. The foam cushions impact, stops parts rubbing against each other, and presents the product neatly when the lid comes off. Send us a drawing or a sample and we will cut the cavity to fit.
