LOVE IT guarantee

If you've used your Jamber coffee mug for a week, and don't love it, then we will send you a prepaid shipping label to return your Jamber mugs for a full refund.  We just ask that you send the mugs in the original packaging (in an attempt to keep them from breaking in transit).

Why You Should Use a Jamber

Jamber mugs were scientifically designed to be exceptionally comfortable and easy to hold, and to be very stable to reduce spills. 

Why does this matter?

Well, this means that Jamber mugs are so easy to hold that anyone can hold them - even if they are suffering from weak grip strength, hand pain, wrist pain, carpal tunnel, arthritis, Parkinson's, or Alzheimer's. 

People tend to drink more liquid when they use a Jamber mug.  And of course, being more hydrated means being healthier, stronger, and more mentally agile.    

    Designed with Science

    Mugs were designed 5,000 years ago, and have not materially changed since then.  (hard to believe, we agree!)

    Jamber Mugs were designed by bio-engineers and scientists, using biomechanics, 3D printing, and 2.5 years of research & development.

        Carriage Hill Assisted Living

        For our 24-resident facility, we have only used Jamber teacups for the past two years. The residents love them for coffee, tea and other hot beverages. They are the perfect size for them and make such a different in their ability to drink and set the mugs back down without spilling. I highly recommend these for any facility and for home use for seniors!

        A Well Thought-Through Design!

        My husband just had his 97th birthday(!) and has some difficulty holding on to most round objects.The Jamber mugs are not only lovely to look at but fill his “holding” needs beautifully. Thank you so much for making his life easier.

        My new favorite cup.

        I love my Jamber cup. It’s light weight, yet sturdy enough. The handle makes it comfortable to grip and the stand on the handle makes me feel secure picking it up and setting it down. I was spilling my coffee at times due to my unsteadiness from arthritis and the effects of cancer treatment. I bought the red and white set of two, but have to get a couple more so I always have a clean one. My husband loves his red one. Thank you for making these cups.
