Just opened a package of these cups and they leak at the seam as soon as you fill them with hot coffee

[This review was collected as part of a promotion.] We love these cups. They are easy for busy families on the go with kids. The thickness is great because hot liquids don’t burn your hand. They are stylish as well and keeps fluids warm!

[This review was collected as part of a promotion.] It is a great paper cup. The material makes it so heat doesn’t transfer too much and it isn’t too hot to hold, but it kept my drink plenty warm for a decent while.

[This review was collected as part of a promotion.] These cups are easy to use and keep drinks hot while being cool enough to cold. They are the perfect size for a cup of coffee or a latte. The drink spout is designed well without spilling.

[This review was collected as part of a promotion.] I love how you can have the hottest drink and you can’t burn your hand. Also holds a lot of liquid. My son uses these for his morning hot chocolate before school 10/10 I’m always buying this!

[This review was collected as part of a promotion.] I feel like these disposable cups were just OK. They did get soggy after liquids being in them for an extended period of time. I’m not sure I would purchase on my own.

[This review was collected as part of a promotion.] Functions well, keeps my morning coffee warmer for longer than a regular cup and makes it easier for on the go drink. It would be even better with a cup sleeve.

[This review was collected as part of a promotion.] This cup is a good size and has good insulation. In addition to keeping hot things hot, it also kept an iced drink cool which was a nice and unexpected perk.

[This review was collected as part of a promotion.] I added very hot coffee and the cup was easy to still hold. It was not to hot where I couldn't carry it. The design is nice and simple and the lids are very study.

My current pack of foam cups leaks from the bottom. I have never had an issue before. I’m guessing there must have been a manufacturer defect. It is a slow leak, but enough to have to wipe where the cup was sitting.
