Three Unique Cardstocks for 3x3 Cards
- 16pt C2S (UV Coating) – A thick CS2 card with UV coating on both sides for a shiny, protective finish.
- 16pt C2S (Matte Coating) – Same thickness as the gloss option but with a smooth, matte finish without UV coating.
- 18pt C1S (UV Front Only) – A more durable CS1 card with a glossy UV-coated front and uncoated back, ideal for writing.
Understanding C1S vs C2S Paper
Paper types are often described as C1S (coated on one side) or C2S (coated on two sides). C1S has a coating on the front only, while C2S has coating on both sides. Coatings can include glossy, matte, or UV finishes, providing different textures and levels of durability.
