Color: Silver, stainless steel mat Size: Length 30cm, Width 38cm Weight: Under 500g The underside has black stoppers to prevent slipping on floors or carpets. If placed in a cooled room, it will feel somewhat cool. You can chill it in the refrigerator for use, but that might not be practical. Bonus: Bag clip for large bags I bought this for my cats, but they wouldn't use it.
