Radical Unschooling Bumpersticker

4″ x 6″ Oval bumper sticker – made from the finest synthetic
(polypropylene  or polyester – similar to vinyl, but thinner and
stronger) materials. We use  automotive-grade color pigments that are
heat-fused onto the material, so the  image is resistant to weather,
carwashes, etc. Bumper stickers are flexible  and easy to apply.
Most stickers will last a year or two under normal  weather conditions.
