1 Color 1 Location - It will be hard to wipe the smile off their faces when they receive the Happy Face Yo-Yo Stress Reliever! This product is not a toy and is not safe for use by children under 3 or pets. Made of polyurethane, each stress ball is manufactured by hand, so no two will be exactly alike. Individually hand printed, placement of second imprint may not be centered. Factory is not responsible if imprint is not fully legible. Imprint will break and appear uneven due to the textured surface.
