Are these leakproof if they were in a lunchbox?

I would say they are. Have two of these and commonly leave them laying on the side while traveling in passenger seat and in my lunch box haven't had a leak yet

I have not tried it in a lunchbox, but I am pretty sure it would't leak there. I have had it in my gym bag tilted over, and it didn't leak.

Yes! I take my lunch in one of these every day and put it at the bottom of my backpack. I don't baby my backpack when going to and from work so it moves around a lot and I have yet to get a leak from these at all.

Definitely. leak free. but pack with a cold pack because it's non insulated and the milk would sour otherwise. also the condensation might be frustrating but wrap in a paper towel in the lunchbox with a cold pack and you'll be good to go. chocolate milk tastes DELICIOUS in this thing.

I have found them to be mostly leak proof. On occasion I have overfilled the soup container. When I do that there is a bit of soup in the bottom of the warming can. It is a case of operator error.

Yes. I have made cheesecake, carrot cake, and chocolate cake in these and never had a leak. The only thing is that it takes a little longer to clean out the tiny grooves.

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.

I've been using these for a couple of years now. I've found that it doesn't leak if the lid is on tight, but will seep after an extended period on its side. So for example, if I find one under the dining room chair several hours after lunch, I will usually find a small amount of water under it. That said, I do send these to school with my little ones.

Yes, definitely. The lid has a good seal and you can tighten it down very tight. I leave these in my backpack which is laid on its side under my desk all day and have never had a leak.

Yes and yes! I used them in our microwaveable bottle sterilizer daily. As for leak proof - they're about as leak proof as a sippy can be. Occasionally little droplets come out if they are dropped from a high chair or thrown across the room but I would highly recommend these cups.

I have to say yes. While I haven't put any liquid in mine, the truly secure way the lids fit would indicate a leak proof seal. The lids will be very tight, almost too tight the first time. I them in warm water to soften and have had an easier time since. Lids are still very tight, but that's how I want them.

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 not had one leak yet. I lay these bottles on their sides in my daughters lunchbox.

Yes. They don't seal tightly unless something hot is inside it. But beware, they can leak. Tried using it to keep lunch warm but knocked it over inside lunch bag. What a mess. Still love the containers, though for when we're at a potluck.

No- the lids stay in place well, but it's not leakproof, so if there is any liquid, it will spill through. Best to keep flat

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 have never had one of these leak. I use them daily either in lunch box or for cold food from the market. Well constructed and dependable best you can use

Yes it will leak into other compartments. Also any wet fruit will make dry compartments wet. I am yet to find a lunchbox that is truly watertight. Another problem with this lunchbox is that none of the compartments will hold a whole sandwich. Other than that I love the lunchbox because it is stainless steel instead of plastic.
