The design is actually sublimated into the entire thickness of the fabric, not just silkscreened on top. Of heavy-duty 360 denier polyester, this flag offers outstanding quality at an affordable price. Flag is single-thickness; design is the same on both sides. Light shining through from behind creates a stained glass effect. Flag will retain its color and beauty for years if displayed in shade or semi-shade, and is rainproof.
