Made by baking in the oven. Coated with oil-resistant and water-resistant coating and baked again for finishing. For a small accent on clothing, hats, bags, accessories, etc. Please refer to the second photo for the size. As this is handmade, there is no guarantee of durability. I would like to sell it to someone who understands this. If you would like multiple brooches or earrings, please comment before purchasing. I will give you a small discount. Oven clay Nordic Hydrangea
