The design is actually sublimated into the entire thickness of the fabric, not just silkscreened on top. Made of heavy-duty 650 polyester, this flag offers outstanding quality at an affordable price. The flag is single-thickness; the design is the same on both sides. Light shining through from behind creates a stained glass effect. The flag will retain its color and beauty for years if displayed in shade or semi-shade and is rainproof.
