Diipoo has four types of materials: blue core cardstock, black core cardstock, plastic PVC cardstock, and A35 thick cardstock. Among them, blue core cardstock and plastic PVC cardstock have similar appearance and thickness.
- Blue core cardstock has a smooth surface and a harder texture, making it suitable for making tabletop games and poker cards.
- Black core cardstock has a patterned surface that forms an air layer. It is a professional paper used in casinos and is suitable for making flower-cut cards or magic cards, and is also relatively high-end.
- Plastic PVC cardstock has a smooth surface and a plastic texture, and can be completely washed with water.
- A35 thick cardstock is a thicker and heavier cardboard. Unlike other materials, it is not a three-layer structure, making it suitable for users who want thicker and heavier tabletop card designs than standard playing cards.
