Care Instructions for Earth are to just f*cking care. All posters are pre-printed on a thin, glossy paper: 100lb gloss text paper. If rolled is chosen, your poster(s) will be rolled into a plastic sleeve. If flat is selected, then your poster(s) will be shipped out flat between corrugated cardboard. We take pride in the quality of all our products and strive to give our customers the best wall art possible!
