The Sienna plein air supply box is designed to work in conjunction with the Sienna pochade box and tripod. The supply box has two adjustable blocks that sit on the front two legs of the tripod. Adjusting the blocks raises or lowers the supply box on the tripod for the perfect working height.
The supply box keeps all your tools within arm's reach and allows you to focus on painting. This indispensable accessory turns your plein air setup into an absolute pleasure to use.
