The folks at Tattly wasn't completely sure that their love for rainbows was entirely apparent, so they took their old Rainbow Set and added a bit more fun. Now with 8 different designs, there is surely a colorful Tattly for every occasion. The Rainbow Set includes the following designs: Color Burst, Rainbow, and DIY Dots by Jessi Arrington; RGB, Magic, and CMYK by Tina Roth Eisenberg; Rainbow Skateboard by Marc Johns; and Rainbow Stripe by Rusty A. Meadows. Tattlys are safe and non-toxic, lasting on average 2-4 days. Printed with vegetable-based ink, they're all made in the USA and fun for all ages! Tattly suggests placing on oil-free areas where skin does not stretch.
