These are acrylic rhinestones in clear and vibrant colors. They have silver settings, making them easy to use for silver-themed decorations. For a size reference, the small bag in the second reference image is A8 size. This means there are approximately 3 to just under 4 of those small bags worth of rhinestones. These parts can be used to create both cool and cute looks, so I hope they find a good home. Thank you for your interest. I have many other items for sale. Please check my profile.
