50 PALM TREE TANNING STICKERS JUST LIKE IN PHOTO, BUT FLAT, NOT ON A ROLL ABOUT 1 1/4" AT LARGEST POINT Tanning stickers are simply paper stickers with skin safe adhesive. People who tan put them on prior to laying in the sun or a tanning bed, the sticker blocks the UV light and leaves a white mark the shape of the sticker to show the tanners progress. These will stick to virtually any non-porous material and the adhesive won't damage the surface.
