Thank you for viewing! These are handmade, very soft bra pads. Both sides are organic cotton double gauze. (The unbleached fabric may have small black dots, which are not stains but are called cotton husks.) Inside, both have approximately 3mm thick 100% linen quilt batting (100% ramie). Diameter is approximately 12cm, and the cup height is approximately 2cm. Please use these measurements as a guide, as they are approximate. We offer a 100 yen discount for combined shipping. If you would like to combine shipping with other items, please let us know in the comments section. We will create a dedicated listing for you. As these are handmade, please refrain from purchasing if you are looking for perfect stitching. As these are delicate natural materials, hand washing is recommended for care. After lightly spinning in a net, we recommend shaping them quickly and hanging them to dry. Some shrinkage may occur due to the natural materials. Thank you for your understanding.
