All one hundred bills?** A: Forget the 10,000 how much monopoly money can it hold i don't want my family stealing from me when i go to the bathroom **Q: What are interior dimensions? Wondering if it would fit an ipad mini and kindle?** A: No, it certainly would not hold a Kindle. I can close it with my car/house keys, my passport, my billfold and my Droid Razr cell phone inside, and maybe a couple of Krugerrands; that's about all. I just made some detailed measurements, and here's what I found:Height (maximum) 1.5", (minimum)1.0"Width at maximum height, 2.75"; at 1.0" height, 3.25""The ends are round and semi-circular; it could hold a narrow object 8.5" long, but the largest rectangular object would be about 6" long, 3" high, and 1" deep - roughly the size of a personal checkbook. I know this is a lot of answer. I hope it helps you, and anyone else who needs to know its inside dimensions. **Q: Is the interior deep enough for 2 or 3 regular size prescription pill bottles?** A: I just went and tried my prescription bottle in it and it fit. My bottle is about 1.5-2 inches around and about 4 inches tall. You could fit about 4 of them in there. I hope this helps. **Q: This is only waterproof, not fireproof or resistant?** A: No small case like this, made out of anything, is fire resistant. small boxes have too little thermal inertia ie too much thermal transmission to be rated as fire proof or fire resistance. Anyone saying anything this size is fireproof is lying. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Strong but lightweight *by on Reviewed in the United Kingdom 10 February 2026* Take this every time I go on holiday - will deter the opportunist thief - well made ### ⭐⭐⭐⭐⭐ Happy customer. *by on Reviewed in the United Kingdom 24 November 2024* This small and not drastically heavy box lets me have a little extra security. I don't trust hotel safes and prefer to use this Lock Box. The dials are a little stiff, but the box is well made and sturdy. Very small amount of valuables like credit cards, money and passport, perhaps some jewellery or a watch will fit in nicely. I don't always use the wire to attach it to some post, just a safe wallet (that does not even look like a wallet) with secure lock, so not to tempt an incidental thief. ### ⭐⭐⭐⭐ Put your stuff in carefully and avoid extreme heat *by on Reviewed in the United Kingdom 19 September 2025* Was really good at first locked easy and felt sturdy however if I didn't have items placed exactly right it did struggle to open after a few days im not sure if this was the orientation of items or something in the mechanism swelling with the heat, big enough for a phone with case a small earphone case and a key card for room maybe a small amount of paper cash just be careful how it is orientated, it is about two - three times the size of a psp and a similar shape. Very eady to set up. Good enough for a holiday myself but would hesitate in buying the same model for someone else without giving them a talk about my experience. ## Frequently Bought Together - Master Lock Portable Small Lock Box, Set Your Own Combination Lock Portable Safe, Personal Travel Safe, ‎5900D, Gunmetal Grey - Apple AirTag 4 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/845014320-master-lock-portable-small-lock-box-set-your-own-combination](https://www.desertcart.dk/products/845014320-master-lock-portable-small-lock-box-set-your-own-combination) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-08-14*
