Suitable for car models: For Opel Grandland EV (Electric) Grooved pattern design: Our car coasters feature a 4D honeycomb groove pattern that captures small amounts of condensation, preventing liquid from pooling in the cup holder. They offer better grip than standard smooth coasters, preventing cups from sliding and reducing noise caused by shifting containers while driving. Easy to clean: They can be easily washed with water when dirty and air-dried or dried in the sun. Keep your car clean at all times without worrying about coffee or beverage stains. Fit – 6.8 cm width: The coasters have a diameter of 6.8 cm and fit most cars. They are also suitable for use at home or in the office—perfect for everyday life. Tip: Please measure your car's cup holders before purchasing. Professional customer service team: We maintain the highest quality standards and offer professional customer service.
