    • Great quality
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
Much bigger than I thought originally! Great quality and very excited to gift this to my brother in law. Waterproof, has a lock combination and even has a spot to put your headphones while in use without getting anything wet on the inside. Fantastic for anyone and on the go!!! Would highly recommend and buy again. ... show more

    • Strong and safe for valuables!
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
Love this!! 5 stars (dunno why one won't light up) Easy to use and holds small valuables/money. It would have to be smashed with something very heavy to break into - I don't think it could be easily broken into, so it is definitely sturdy, strong and safe. Easily fits into my night table drawer. Small enough to pack into a suitcase for travel. Highly recommend! ... show more

    • Pretty good safe
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
If a criminal wants your stuff inside, they will get it and this wouldn't work. This isn't Fort Knox...but if you're at a water park or amusement park, and wanna tether a small safe to a pole to put your keys or phone into...this is perfect (That's what I'm using it for). This is a pretty decent safe. The wire that connects to it is coated in plastic and pretty long. I really don't know if there's any metal in the safe to make it more difficult to break into. But I wouldn't use it for anything super valuable. But it's a decent item for under $20 ... show more

    • Perfect Little Safe for Peace of Mind!
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
The Master Lock Portable Small Lock Box has been an incredibly useful addition to our household. It’s compact, sturdy, and perfect for securing important items like cash, IDs, keys, and small documents. I really appreciate the “set your own combination” feature - super easy to personalize and even easier to use. Its portable size makes it great for travel, dorm rooms, or just keeping valuables tucked away at home. It’s lightweight but still feels durable and reliable. I love knowing that important items are protected without needing a big, bulky safe. The safe is easy to open and I find it very useful when traveling. Overall, this little lock box offers great security, convenience, and peace of mind. Highly recommend for students, travelers, or anyone who wants a simple and effective personal safe! ... show more

    • Compact, secure, and travel-friendly – A must-have for peace of mind
Color: Gunmetal Grey Size: 9.8 x 5.5 x 2.6 inches
I’ve used the Master lock portable small lock box locally and on 2 trips, Vegas and Cancun, and I can confidently say it’s one of the smartest purchases I’ve made for protecting my valuables. Whether I’m on the go, at the gym, at the beach, or just need a secure place to stash items in my car, this lock box delivers outstanding performance, durability, and peace of mind. The customizable 4-digit combination lock is easy to set and eliminates the hassle of carrying or potentially losing a key. The locking mechanism feels solid and responsive, giving me confidence that once it’s locked, it’s truly secure. It’s strong enough to deter opportunistic theft and gives me assurance when leaving items unattended in public settings. Don’t be fooled by the term "small" — the interior space is very well-designed. I can comfortably fit my phone, passport, small wallet, keys, and even some jewelry with room to spare. The foam lining inside is a thoughtful touch that prevents my items from shifting around or getting scratched. It’s also a good size for securing medication if needed. This lock box truly shines in its versatility: Beach trips: I loop the cable around a beach chair or inside my beach bag. I can swim without constantly worrying about my phone or car keys being stolen. Hotel stays: Not every hotel has an in-room safe, and this box is a great portable alternative. Car security: I’ve used it to store cash or spare keys in my car when I don’t want to carry them into the gym or on a hike. Airbnb or shared living spaces: It adds an extra layer of security for valuables when you're staying somewhere unfamiliar. The included cable loop is extremely handy — it allows you to secure the box to a fixed object like a bed frame, chair, railing, or inside your trunk. It’s coated in plastic to avoid scratches but still strong enough to resist cutting or tampering. The outer shell is made of impact-resistant ABS plastic, and the internal foam padding protects delicate contents from damage. It’s also water-resistant, which is a big plus for beach or outdoor use. It’s not waterproof, so I wouldn’t submerge it, but it can definitely handle splashes and light rain without issue. This is an excellent all-around lock box for anyone who values security, portability, and peace of mind. Whether you’re a traveler, student, athlete, parent, or just someone who wants an extra layer of security in unpredictable environments, this product is a fantastic choice. Pros: Customizable combo lock – no key needed Foam-padded interior to protect contents Water- and impact-resistant exterior Compact but holds a surprising amount Strong cable for tethering to fixed objects Affordable and well-built Cons: Not fireproof or waterproof (but not designed to be) Cable can be a little stiff at first use Would I buy it again? Absolutely. In fact, I’ve already ordered a second one as a gift! ... show more
