Innovative design: Thanks to the central sink, the cigarette butts can be put into the water and put out, then put into the ashtray, which is more clean and hygienic. Windproof design: The ashtray has a lid and its container is deep and large enough to store many cigarette butts and keep the ashes inside. Careful design: Three small grooves make it very easy to place the cigarette. Bottom design: smooth and stable at the bottom. Dimensions: 11.2x 9cm
