Flat Greeting Cards - Vertical (3.5 x 5 inches, single-sided) are available in two durable options: 14 pt. Gloss and 14 pt. Matte cardstock. Both feature thick, stiff paper with an aqueous coating for added scratch and scuff resistance. The Gloss finish offers vibrant colors and sheen, ideal for business cards, postcards, hang tags, and pocket folders, though writability is not guaranteed; ballpoint pens and permanent markers work best. The Matte finish provides a non-reflective, elegant look with better writability, though testing is recommended. Both cardstocks are sourced from sustainable materials, with size variance of +/- 3mm.
