The eco-conscious Blue Bottle Love bottles are made of break-resistant Italian blue glass, so they weigh more than most. But they’re showstoppers, sandblasted with loving inscriptions and positive intentions. (Blue Bottle also sells a variety of hemp slings to make toting easier.) Blue Bottle Love’s philosophy is based on the belief that the molecular structure of water is affected by words, vibrations and light — so the bottles are made to allow sunlight to pass through. Prices vary according to size.
