humangear STAX, Stackable Snack Containers - 4-Piece Leak-Proof Snack Travel System - FDA-Food Safe, BPA/PC/Phthalate-Free - Stackable & Click-Together Food Storage, Medium

I’ve looked for years for containers that are truly leak proof, and finally, I found it! Even with thin liquids (like water) this container simply does not leak.. It’s handsomely designed, with great attention to detail. It’s sturdy, not at all flimsy. I highly recommend this product.

I think you could use this for so many things and it’s so convenient. I love this company and they make really great products.

The orange lid in my bento box is from this set, it's holding course salt for my egg. I've been looking for small carrying containers for years and saw these in a YouTube video. I'm carnivore and these little containers are absolutely perfect for my purse. I carry butter, salt, spices, dressings, and meds in them. I love that they lock together and best part is they stay locked together at the bottom of my purse making them easy to find. Each tiny container has its own screw on lid so you can use them individually or stack 2 or 3, you are not limited to taking all of them every time. These are the perfect size to use in my bento box for sauces and salt. They are high quality and water tight. The lids fit securely and you can carry dressings or vinegar and oil for salads. They are so darn cute I bought two sets.

I bought these almost 2 years ago and i fell in love. I use them for coffee on every camping trip and it still seals everything i put in it. Definitely going to be buying a bigger set soon to store food

I thought I really wanted the magnetic toiletry containers—you know the ones. But I couldn’t justify the price and decided to give these a shot. These far exceeded my expectations. I purchased two packs of the small set. I have put them through the wringer already, even have my liquid foundation in one, and no leaks. I’ve been on 21 flights since I purchased these, plus hours and hours of travel and these hold up beautifully in my bag.Pros: clear and easy to identify what’s inside; seals with a rubber o-ring/gasket; clicks together to make as tall or short of a stack as desired so can fit in any size cosmetic bag; varying sizes; affordable; pressure differences during travel don’t affect theseCons: one container wouldn’t seal and I realized the silicone o-ring was popped out a little; upon further inspection, I realized the o-ring was enormous and was simply crammed in there so it wouldn’t seal. I replaced it with a properly sized o-ring and it works now, though the lid is still bent from the initial o-ring that was in there. Probably just a random defect, but I can’t stack that particular container because it got messed up (though still seals).

I have several sets now, different size groups, and use them all. For my own cooking, delivering meals for friends, storage in the fridge. Have their own lids, so no need for baggies or plastic wrap. Stacking is great, keeps everything together so can find item quickly.I've done several Meal Trains recently, and these were great for delivering salad dressing, balsamic reduction (!), salad toppings, dessert toppings, crumbled bacon, grated lemon peel, chopped nuts; one size is perfect for a 4-oz can of chiles. Great for pre-measuring cooking and baking ingredients.Cooking for one is a challenge, these help to handle leftover seasonings and garnishes so you don't have to eat 4-6 servings - basically a whole week - of the same dish. Highly recommended!

I use these for so many different things when I’m traveling. They’re great. I can even put liquid in them when I’m traveling and it doesn’t leak.

Love these!I have MANY, use them for everything!Very durable.
