Let us know in the comments 👇 Fun fact – some of these bracelets are measured in grains, rather than grams. A grain is an old unit of measurement that is still used for some things today. One grain is equivalent to 0.065 grams, and was traditionally based on the weight of a single grain of barley 🌱 Get guessing – we’ll be revealing the answer in 5 hours ⏱ Our online shop has a selection of bracelets inspired by the collection, including ones like these.
