This is a mini Zen Garden, complete with fine white sand, rocks, a wooden rake and a concrete planter.
The word Zen (or Chán) is a type of Buddhism that emphasizes inner peace and concentration. Raking the sand and arranging the rocks in this mini Zen garden will promote calmness. It's mindful and peaceful.
It looks good in a home or office setting and encourages tranquility. It's almost meditative playing with it.
It makes a great gift as it looks beautiful and encourages mindfulness.
