Cuppow Wide, Orange BNTO Canning Jar Lunchbox Adaptor - 6oz.

The cup is so thick around the edges that it doesn’t let you seal the container so it’s no longer leak proof, the purchase comes with only one cup and for $10+, it’s not really worth it. It’s more cost efficient (and mess-less) to just buy little separate Tupperware containers for sauce/dressing/granola etc to ensure nothing leaks.

I this cup use for packing almond milk for my granola to bring to work. It works with my wide-mouth mason jar and it doesn't leak. My only complaint is that for the cost (at least when I bought it), it's not worth it for just one cup.

Like so many others I do the whole salad in a jar thing for lunch. These come in handy keeping the dressing or croutons separate from everything else and I can meal prep more ahead of time because of it. If they were glass (I switched to jars to break the whole plastic cycle) I'd give them 5 stars...

Super cool idea! I was tired of trying to get 2 containers into the lunch bag without spilling anything. I'm going to get some of the ones for the regular size jar opening as well. I have several of the quart size "drinking jars" that were so popular some years ago. They have a handle on the side and make it easier to carry. I also bought 4 others for my grandson and his almost-bride. They were thrilled with them. Summing up, the best thing is that the container with dressing for salad CAN'T spill!!! The lid can't come off like some of my previously used plastic containers.

Not quite what I expected. My wife was excited to get this in but when she opened it, it was one more of a ohhh. It came in just a plastic bag, not the packaging displayed. Overall look cheaper than expected especially for the price tag. Will hold on to this one see how it last.
