They don't appear to be sold in craft stores, we checked the basics (Michaels, Hobby Lobby, Joanns) and came up empty handed, but have tracked the down at office supply and art supply stores. They're available for purchase in 4 or 8 packs and prices vary accordingly. Read more over at the Sharpie Stainers website.
They'd be awesome for slumber parties and birthday bashes. Try customizing a tshirt, shoes, hair accessories and more. They'd also be awesome to design your own curtains, linens, pillows, or possibly even carpet tiles — look out now!
