Handy Safe for travel cash
Color: Gunmetal Grey
Size: 9.8 x 5.5 x 2.6 inches
I think it is TSA compliant, have not taken it anywhere but home. It is small. maybe enough for a cellphone and some cash. I have been able to fit 400 dollars in one very easily. The attached cable is a think bike lock wire sort of affair. a pair of bolt cutters and it's game over. But for routine security, perfect. You wrap it around a sturdy base like a radiator or bathroom pipe and all is well. Changing the 4 digit code is fairly easy with just a screw driver. Keep in mind though nit only opens to like a 45 degree angle so do not try to force it all the way back. It's hard plastic, not metals and you will break it. The code reels are little rotary thumb disc with the number visible but not at low light. If you have chubby thumbs use your index fingers to spin it to the right digit. Perfect for hotel stays or for when your Uncle comes to visit. You know the one, seen only during funerals and holidays with large food and alcohol events. It is slim, maybe a cell phone or passport wide but plenty roomy for cash, foreign and domestic. over all not bad a the price is right. Plus you can change the combination as it suits you

love it!!
Color: Gunmetal Grey
Size: 9.8 x 5.5 x 2.6 inches
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.

good 👍
Color: Gunmetal Grey
Size: 9.8 x 5.5 x 2.6 inches
Works well. Except I don't know how to set the code, there was no instructions. And the buttons don't always work at first, but i can always get them to work eventually.

Great little travel lock box
Color: Gunmetal Grey
Size: 9.8 x 5.5 x 2.6 inches
This is great. You can program what 4 digit code you want. It has a cord that wraps around the cade for travel and will unlock on one side so you can wrap it around something sturdy so it can't be taken. It will hold a thin ish wallet and like your passport, glasses or phone. It had no problem holding my metal wallet. This case itself is made of plastic but the cord is, i believe, metal. Used this on a beach hooked on my chair and nothing inside got wet.

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!

Didn’t work for me - heavy & large
Color: Gunmetal Grey
Size: 9.8 x 5.5 x 2.6 inches
This didn’t work for me. It was heavy, large & clunky. Not suitable for travel unless you’re checking luggage & packing a bit light. Definitely high quality just wasn’t what I needed.
