Just received the cups and immediately washed and tried one.
It is all that I hoped for. Elegant and beautiful, lightweight and easy to carry, convenient to use, and leakproof including when carrying it after use and before washing.
I was worried about drinking through the top cover as there is no airhole, but the cup’s elasticity solved this while still being rigid enough for holding.
Unfortunately, as we are still in lockdown, I will not get many chances to use it as of now but I look forward with hope.
I’m glad I got 2 of them as the second one is going to be a very special gift for a very special friend.
Thank you for thinking out all the fine details and producing such a practical and beautiful product.
