Will these tubes and caps securely hold liquid in a lunch box/snack bag without leaking or opening?

Not sure. I used them for powdered candy. I would say no though. It leaked from them .

The lids fit snug. The dividers are deep. As far as leak proof, I'm not sure what you plan on doing with them. If closed and left upright I don't see them leaking.

If these bags are tied tightly they don't leak ever. I am very pleased using them for wet food scraps.

The lid is screwed on, not snapped on. My wife and I use it for salad dressings in our lunch bags. It doesn't leak when tipped over in a lunch bag. (even vinaigrette or Italian dressings)

I did not have any problems with leakage. I have used them for transporting pickles, making jello shots and putting condiments in to take for lunch.

They Don't leak... But you need to make sure you "snap" the lid close. if you don't hear the "snap" its not closed. :-)

Yes - they are great and I use them for my son's lunch and snacks on the go. No rust and easy for them to open, they seem to seal tight and not leak. Lightweight as well. I would recommend these! 1/4 cup (small) and 1 cup estimate (large)

They would hold liquid if you tighten the lid enough, but they would be messy when you open them if they are shaken in transportation.

I would say yes, as you have to fill them in an upright position - I use a freezer safe cup, or the fluid will leak out around the cap, before the are frozen.

Yes the lids seem airtight to me. They have screw on grooves that secure on pretty well. Interesting idea to use them for dry snacks. Will have to try.

No, it doesn't, and they are not leak-proof, although I do carry them in my lunch bag sometimes. They work well for thicker items like a smoothie or yogurt, but I wouldn't recommend them for liquids like juice or soup, unless it's just going in your fridge.

I have never had a problem with liquids leaking. I use the smaller sizes in my lunch bags and have never had a leak. The others don't get shaken much unless I'm using them for a marinade, which get shaken gently, but again, no trouble. I like these a lot.

I would trust it in a lunchbox. Never had an issue with leaking. The design is great. It is slightly curved but nothing too dramatic. It would be safe to call it mostly flat.

The lids are actually almost a too snug, so it's doubtful the contents would spill during transit. But they may vary from one set to the next, so you would probably want to use a bit of scotch tape just to be sure.

Yes, they lock in place and have had no problems with leaking. It really is a nice set of containers.

I use the small container for yogurt...have never had a leak...otherwise the compartments are used for veggies, meat & breads & I have never had a leak out of the lunch kit...I use a cyropack ice sheet which fits perfectly in the pouch inside the lunch bag & the lunch kit stays cold for hours. I also use a 'juice in the box' container for drinks which fits perfectly in the outside pouch.

I lay these sideways in my daughters lunch box and they have never leaked. They work really well!
