Designed to elevate the storage, protection, and aesthetics of button battery sets, our cases are precision-crafted for the three most widely used button battery models: CR2016, CR2025, and CR2032. Made from premium 304 or 316 stainless steel, these cases blend exceptional durability with functional versatility, making them the ideal choice for consumer electronics, industrial applications, and customized gifting scenarios.

• Premium Material & Reliable Protection: Crafted from 304/316 stainless steel, the case offers excellent durability—304 for daily corrosion resistance and 316 for enhanced anti-rust performance in harsh/humid environments. It effectively shields CR2016/CR2025/CR2032 battery sets from impacts, dust, and moisture, preventing short circuits, leakage, or battery damage during storage and transportation.
• Customizable Surface Finishes: Supports two tailored surface options to meet diverse needs. The sleek smooth finish complements high-end electronic devices, while the custom engraving service (for brand logos, model numbers, or personalized patterns) adds unique identity, ideal for promotional gifts, corporate branding, or specialized industrial scenarios.
• User-Friendly & Versatile Design: Features a compact, lightweight structure that fits seamlessly into packaging, toolkits, or carry bags. The secure yet easy-to-open closure ensures quick battery access, making it suitable for multiple scenarios—from smart wearables' spare battery storage to medical device battery organization and branded promotional kits.
