This set was masterminded by our 2nd Kickstarter Backers. Many of you requested a set that was made from various woods representing each color of the rainbow. Well here it is. For Red we have Bloodwood. For Orange we have Chakte Viga. For Green we have Lignum Vitae. For Yellow we have Yellow Heart. For Blue we have Blue Mahoe. For Indigo we have Rainbow Poplar. And for Violet we have Purple Heart. All contained in a compartmentalized Maple Dice Box.
