Never before has air in my home traveled so fast from one side of a mug to the other as with through the wormhole in this mug!

The wormhole opens unforseen doors of opportunity (when blown through it, it is a wind tunnel and using a simple broomstick allows for easy stacking of multiple wormhole mugs!)

Yet, despite the hole, it keeps my coffee where it should be!

I love it. I set a notification since I missed the last restocks so I bought 3 mugs the moment I got e-mailed. 1 stays at home, 1 for work and 1 for a friend. So I started with a super massive wormhole hence the photo and the three angles of the packaging. Great size. Perfect to hold, even through the hole. Funnily enough the hole isn't as obvious to my coworkers as I thought when sitting at my desk and the mug resting below eye level. Print for all three is high quality and centered for the hole on both sides. Rim is thicker than normal mugs but that doesn't hurt.

Overall the perfect mug. I would also buy a bigger version of it, I also love my basic 650ml mug I had before. A combination of both would be mind and gravity blowing but probably also a little heavy.

Thank you for sharing so much love on the Wormhole Mug. A bigger mug would be awesome! We will surely pass this on to the team when creating and improving our products 🙏

I like the illustration on it, and I like the concept. It’s a bit of a chore to clean (if you don’t want to put it in the dishwasher because you’re afraid the paint will come off). But I think it’s a cool mug.

It is amazing, I love it! Easy to hold, fits a lot of liquid. I use it for my everyday tea. And the design is so imaginative, I surprise myself getting lost looking through the wormhole many times!

We're so glad to hear that, and thank you for the gorgeous photo! 😍

The mug arrived safely and securely, well-packaged, after a slightly longer delivery time (though I was notified of this by email). It’s a present, and the recipient is sure to be absolutely delighted with this unique mug! I haven’t found any other mug that’s quite as special!

At first I was scared that the mug will be too small, but thats definitely not the case. The art on the mug is beautiful and great quality. My friends all loved it too and looked at me like this: :0 haha

I've been wanting one of these since they first came out but always missed the re-stocking. Now I have one and am not disappointed. My geeky heart soars as I sip my tea with a hole in it.

As soon as I received this mug, I felt the immediate need of drinking a coffee or tea in it. It is mesmerizing, the quality is great and I absolutely love it. I thought that it could be a bit of a challenge to clean under the wormhole, but this proved not to be a problem, specially since it is dishwasher safe. I can only recommend this amazing mug!

I’ve already ordered my second Wormhole Mug.
The mug is very well made, and even after lots of washes in the dishwasher, it still looks as good as new.

I can't help thinking it is painful to clean by hand... But godduck, does it look dope in the cupboard

Great mug, but why on earth did you put an impossible-to-remove label on the bottom?

As a student who forgot to bring a mug when moving in, it fills its job pretty well.
Sure it’s a bit pricey, but hey it is unique, really cool to have and supports one of my favorite channels. I love it!

We love, love, love the design, and the quality is also great! The only thing is: it's not easy to stir your drink in a wormhole mug..

It looks great! i really loved it but it;s not so convenient to drink from it. The inward-rolled rim of this mug makes it uncomfortable to drink from. That;s why 4 starts only instead of 5

Hi Piotr, thanks for the great feedback, and we’re glad you love the look! The inward-rolled rim is part of the design since a wormhole mug needs a wormhole, otherwise what’s the point? We know it takes a little getting used to on the drinking side, but we hope you come to enjoy it. Either way, this is helpful for us and we will consider it when improving our mugs. Thanks for all the amazing support 🥰
