Chinese Shandong Province Crafts - Set of 2 Chinese Antique-Style Paperweights These paperweights contain fossils of trilobites from the Paleozoic era, and are known in China as "bat stones" because their patterns resemble bats. While fossils of just the body or closed wings are seen, I believe fossils in this form, with the wings open, are rare. When you lightly tap them together, they produce a high, pleasant sound. Size: 18cm x 3.4cm x 1.5cm - 1 piece Woven cloth case size: 20.5cm x 10.7cm x 3cm Weight: Approximately 270g/piece (Please allow for slight variations as these measurements are approximate.) They have been stored in a closet for many years without being used. Please refrain from purchasing if you are sensitive to items stored in a private home. (There are multiple items, but since they are all natural products, the patterns vary, and there may be cracks or chips in the fossils. Please understand this and only purchase if you appreciate these characteristics. Also, if you would like to purchase multiple items, we can offer them at a very low price due to shipping costs, so please comment.) We have many other items for sale, including antiques and vintage items. We offer combined shipping discounts, so please take a look.
