Does the thought of confronting your housemate send you into a spiral of existential dread? Have you had your lunch nicked from the work fridge one too many times? Boy, have we got the gadget for you!

If a passive aggressive note just isn’t cutting it, allow us to introduce the snack safe; a compact safe, secured with a combination lock to keep those pesky housemates away from your leftover dim sims.

Made with a food-grade polycarbonate that’s compatible with both refrigerators and freezers, this nifty little box features a three-digit lock and air vents to keep your delicious, prohibited snacks fresh. It also has a seven litre capacity so you can rest smugly knowing that your cupcake, knock off beer, and soy milk will all be right where you left them when you get home.

The best part about the snack safe – aside from the Everest heights of pettiness – is that the lockbox is transparent, so your roomies can see just what forbidden fruit they’re missing out on. 

And while there are slightly more mature reasons to invest in a fridge safe like, let’s say, keeping medications away from curious children, most folks on the internet have vengeance on their minds. 

The company that has taken passive aggression to new heights is UK-based Lockabox, and Snack Safes can be purchased directly from the businesses website.
