Shanghai Kuntu Industrial Co., Ltd.’s “carry on safe box” series is a compact, travel-friendly security solution designed to protect valuables like passports, cash, laptops, tablets, and jewelry during air, train, or road travel—while complying with airline carry-on size restrictions. Unlike bulky travel safes that may be too large for overhead bins or under-seat storage, our carry on safe box prioritizes portability without compromising security, making it ideal for business travelers, families, and tourists worldwide. Backed by over 20 years of manufacturing experience and BSCI-certified quality control, these safe boxes are trusted for their durability, TSA compatibility, and user-friendly design. The construction of our carry on safe box focuses on balance between size, security, and travel practicality. The box body is crafted from lightweight yet durable aluminum alloy (weighing 3–5 pounds) or high-impact ABS plastic (2–3 pounds)—both materials resist scratches, minor impacts, and tampering. The external dimensions (typically 14”x9”x6”) comply with most airline carry-on standards (e.g., TSA, IATA), fitting easily in overhead bins or under airplane seats. The locking mechanism offers two travel-friendly options: a TSA-compatible combination lock (allowing airport security to inspect the box without damaging it) or a key lock (for users who prefer traditional security, with two spare keys included). The interior includes adjustable foam dividers to organize valuables (preventing laptops from scratching against passports) and a small zippered pouch for cash or credit cards. For added convenience, many models feature a built-in handle (for easy carrying through airports) and a steel cable (to secure the box to hotel room furniture, like bed frames or desks, when not in transit). A notable case involves a business traveler from Germany who uses our aluminum alloy carry on safe box for monthly international trips. The traveler reported that the box fits easily in overhead bins on flights to Asia, Europe, and North America, and the TSA-compatible lock has never been damaged during security inspections. The foam dividers keep their laptop (13”), tablet, passport, and travel documents organized, and the steel cable allows them to secure the box to hotel furniture—eliminating the risk of theft from hotel rooms. After 18 months of frequent use, the box shows no signs of wear, even after being placed in crowded overhead bins. For families traveling with children, our ABS plastic carry on safe box is a popular choice—it is lighter (2.5 pounds) for parents to carry and features bright, kid-friendly colors (blue, pink) that are easy to spot in busy airports. A family from Australia used this model during a 6-week trip to Europe, noting that the box held their children’s passports, extra cash, and small toys, and the combination lock was easy for parents to set and reset (they chose a simple 4-digit code tied to their children’s birthdays). Our carry on safe box series offers multiple models to fit different travel needs: - Slim (14”x9”x4”): Ideal for laptops (13” or smaller), passports, and cash—fits under airplane seats. - Standard (14”x9”x6”): Suitable for laptops (15”), tablets, jewelry, and multiple passports—fits in overhead bins. - Expandable (14”x9”x6”–8”): Features a zippered expansion panel for extra storage (e.g., souvenirs purchased during travel). Our commitment to cross-cultural adaptability ensures our carry on safe box meets regional travel needs. For example, in countries like Japan (where airline overhead bins tend to be smaller), we offer the slim model as a top recommendation. In the United States (where TSA inspections are common), we emphasize the TSA-compatible lock in marketing materials. Our foreign trade team also provides multilingual instruction manuals (including Japanese, Spanish, and Mandarin) and offers custom branding (for corporate clients, like travel agencies or multinational companies, to add their logos to the box). Every carry on safe box undergoes rigorous testing at our Shanghai factory, including: - Size compliance tests: The box is measured against 20+ airline carry-on standards to ensure compatibility. - Durability tests: The box is dropped from 3 feet onto concrete (simulating airport handling) and shaken for 1 hour (simulating turbulence). - TSA lock tests: The lock is tested with TSA master keys to ensure security agents can open and re-lock it without damage. We also offer customization options, such as adding a USB port (for charging phones inside the box) or a waterproof lining (to protect valuables from spills).

We can provide samples of different models and offer bulk pricing for travel agencies or corporate travel programs.
