Master Lock Small Travel Safe with Cable, Gray Combination Lock Box, 5900D

I own two of these because I loved my first one so much that I needed one for my mom’s house too. They are super easy to use and figure out while setting it up, and the perfect size!!! super easy to bring around or keep hidden somewhere in a room. These things don’t budge if you don’t put in the exact code!! Great quality, my only wish is it would be nice if the lid opened a little more than it does because it doesn’t open all the way up, it stops before even reaching a 90° angle.

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!

It’s absolutely perfect except the freaking numbers are so difficult to rotate

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!

This is a genius idea. I go on solo adventures and swimming at the beach will be a lot less stressful now that I know I can secure my stuff to a tree. Part bike lock, part safe, works great.

Firstly, if you are looking for an indestructible safe to hold large items, this is not the safe for you. This safe work great as long as you use it for it's intended purpose. To keep your small valuables relatively secure while in a moderately safe environment. Example: Using it while on vacation to prevent room service from accidently "cleaning" your wallet or phone. Or, if you have small children around and want to keep them from your medicine, phone, etc. Now, if you plan on attaching this portable safe to a light pole and storing your Rolex and Bentley keys in it while you go for a long walk in Central Park, well... you might be disappointed. The safe is heavy duty and would take some effort to pry open. But the body is plastic so this safe could be defeated with a pry bar or hammer. Bottom line, this product is meant to be as a safeguard and deterrent, not an impenetrable safe. If you keep this in mind you will not be disappointed. I am glad that I purchased this safe and feel safer (no pun intended, well maybe) leaving items in my hotel room when heading down to the gym or breakfast.

Well, the item is as described. It has a combination lock, a cable to chain to something for security, and a compartment to put things in. But, the button to open it is jammed and I cant use it. I tried product support several times to no avail. A waste of money.

I like this box a lot. I feel a lot safer travelling with it. At the airport, it's nice to have my jewelry and passport, extra credit cards, etc. locked up when the lines are long (still carry cash in palms tho). At TSA, bags get stopped or stuck in the machine, and you don't know whose what is being gone through for a few minutes, it's nice to know they couldn't take advantage (not that I suspect that but it has been documented that there are some bad apples out there!). I've never been asked to open the box, so it must be fine to see through. And I like using it during my stays where there might not be a safe. The only thing is that if someone really wanted to steal the whole box, it probably wouldn't be that hard. The wire chain doesn't appear to be super robust.

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

justo lo que pone el producto

Take this every time I go on holiday - will deter the opportunist thief - well made

We used this on our cruise ...worked wonderfully! It's easy to use and set (and reset) the combo (after watching YouTube video). It fit our phones and money and cards ...anything we needed to keep secure while at the beach or on the ship. It is a bit heavy! this is true. But for the price, compared to other such gadgets (available to me in Canada, that I could find, lol), and its quality of use, I won't complain! I look forward to using it again on the next trip! :)

Ótimo para guardar pertences pessoais, evitando incômodos!
