Let them know you're rooting for them with a keepsake card that's hand-crafted from sustainably-harvested birch wood. Single card and coordinating envelope are packaged in a clear sleeve. The back of the card is blank. Wood veneer is thin enough to not require extra postage, yet flexible and durable enough so that it can be mailed safely (approx. 1/32" thick). Designed and produced in the USA. 100 percent biodegradable and recyclable with paper goods. Size: 4-1/4" x 5-1/2"
