Our posters are shipped in triangular kraft boxes to ensure safe delivery and avoid using plastic caps. In several locations, we use stay-flat envelopes for small-size posters. Big-size posters are shipped in mailing tubes or triangular/rectangular tubes Framed Poster Packaging The posters are placed within frames upon arrival. The frames come pre-packed with corners and wrap and then packed in a box with strong edges to protect the frames. I-beams are used in addition, to give the package additional sturdiness and for multi-item orders (max 3 frames in one package). Free standard delivery to the US, UK, EU, CA & AU.
