The big difference between this incense holder and the conventional ones with similar designs that you can find in stores in your city, is that they are handcrafted one by one... thus becoming a unique piece. We manufacture each of them in small batches and they may have a small bubble or difference between one or the other and they are not considered a defect but rather a special characteristic of each piece. Measures: 3 cm x 5 cm Weight: 90g Material: Grey cement (made and polished by hand).
