These are a gorgeous sustainable set. Four round dipping bowls and 1 rectangle serving tray on which to place them.

From their website:

"Handcrafted from one solid piece of acacia hardwood, each wood tray, bowl, and spoon has its own unique look with a naturally colored wood grain. Each piece is like its own work of sculptured art!

Acaciaware™ is made from acacia wood which is a hard wood with a tight grain. This superior material makes our wooden serving bowls resistant to water penetration, stains, and odors."
