1. Spanish playing cards: This is the most accurate description, as Spanish dice are usually used in conjunction with Spanish playing cards for games like "mus" or "chinchón".
2. Dados: This is the Spanish word for dice, and you could use it in English, though it might sound a bit strange.
3. Dice: This is the most general term for the objects themselves.
4. Specific type of dice: If you want to be more specific, you could mention the type of dice used in Spanish games, like "five-sided dice" or "domino-style dice".
