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.

        Snowstorms delayed the delivery

        Wonderful cups!! In spite of the worst snowstorms that brought the Seattle area to a standstill, this small company kept in touch with me. I recommend this company for its excellent service and amazing products to help us with Parkinson’s.

        Excellent Product

        My friend with Parkinson's was thrilled with the cups. They are easy to handle and the grip is very comfortable even though she has relatively small hands. Thank you so much for this invention!
