If you’d like to offer more support, let me offer you this Mathematical Buddha Bottle to bring Blessings to your Day. Plainly, it's a standard, 17-ounce, double-walled stainless steel water bottle like the one you already use for your daily work, workouts, hikes and picnics. Keeps your drinks hot or cold for hours, odor- and leak-proof. And the people who make it for you give me a 30% donation. Hooray.
