About SuLiao In 2012 Su and Liao discovered a mutual love for hourglasses completely by accident. The couple was brainstorming ways for Liao to continue to be a stay-at-home Mom and still have an income. Before long they had created an online store featuring products made in their hometown. Along the way, Liao was able to find a gentleman who produced gorgeous sand timers from the workshop on his farm. After visiting the workshop to learn how the hourglasses were made and see just how stunning they were in person they realized they might be onto something. The reloj de arena quickly became the star of the online store. The next year " SuLiao " brand was born.
