Selecting the material depends on your brand positioning and protection needs. For premium brands, EVA pouches or PU leather cases offer a luxury feel and high durability. For eco-conscious markets, prioritize FSC-certified paper boxes, biodegradable PLA, or recyclable PET. If the goal is retail visibility, high-transparency PVC or PET cylinders allow customers to see the brush bristles clearly. Ensure all materials are BPA-free and meet REACH or RoHS standards to avoid chemical leaching into the brush fibers.
