Our cube can be engraved with a letter of choice on each side. Go for four different initials and let us engrave your initials or the initials of your loved ones, make a word or choose the same letter on each side. We think it’s the perfect gift and we like to gift and collect more of them and wear them on a necklace or on a cord like our model. Each cube can be a memory of a special occasion. 3x3mm. Sterling Silver. *We have updated the cube and made it stronger and heavier.
