Master Lock Portable Small Lock Box, Set Your Own Combination Lock Portable Safe, Personal Travel Safe, 5900D, Gunmetal Grey

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.

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!

Love the safe. Works well on my trips. I do wish it was just a little bit wider. I had to take my passport out of the holder for it to fit. That is my only con at the moment.

Perfect for a beach vacation! This lock box is compact, easy to set your own combination, and keeps valuables safe while you’re out in the sun. Sturdy, well-made, and very convenient—fits small items like keys, cash, or cards. Makes me feel secure while enjoying the beach!

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!

I really wish that I had done more due diligence on this. I actually bought this twice before I came to the horrific realization that this is the biggest source of false security that I have ever seen or heard of. As other reviews have mentioned; it’s INCREDIBLY EASY TO REMOVE THE HINGE PIN. What’s even worse- IT CAN BE REINSTALLED VERY EASILY AS WELL. If someone wants to gain access to your things; they don’t even have to bother with figuring out a 4 digit combination (which is alarmingly easy as well)- they can just use a paper clip, SIM tool, etc. to slide the hinge pin out & back in without you being any wiser. For the cost of this product- you can purchase a similar product with a much better hinge mechanism; though the lock isn’t quite as secure. You’d be better off to buy a clear plastic waterproof container & use a luggage lock than fool with this thing. I wouldn’t even give this to a kid to secure his lunch money…. I feel so stupid… TIMES (2)!

High quality, great design, thoughtfully priced. Strong, easy to open. Would recommend in the future!

Funktioniert sehr gut. Schloss hakt ein bisschen aber ansonsten top. Ich hoffe es muss nie seine Brandfestigkeit beweisen.

justo lo que pone el producto

Fulfills its function. Might feel a bit cheap and plasticky but that’s exactly what it was.

Use it when overseas

Great quality, good weight, easy to use, keeps your stuff safe, value for money, great product and excellent quality, strong little safe,
