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 ### ⭐⭐⭐⭐⭐ Awesome *by A***A on 18 April 2023* Superb ### ⭐⭐⭐⭐⭐ Secured and safe to use *by S***A on 21 July 2019* A must have for person staying / sharing accommodation specially students ### ⭐⭐⭐⭐ Good product 👍 *by A***L on 14 July 2021* Nice buy ## 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.be/products/116016817-master-lock-5900d-set-your-own-combination-portable-safe-9](https://www.desertcart.be/products/116016817-master-lock-5900d-set-your-own-combination-portable-safe-9) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-20*
