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 specks, which are not stains but are called cotton husks.) Inside, both pads have approximately 3mm thick 100% linen quilt batting (100% ramie). Diameter is approximately 11.5cm, 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. Please refrain from purchasing if you are looking for perfection in the stitching, as these are handmade. As these are delicate natural materials, hand washing is recommended for care. After gently removing excess water in a net, it is recommended to shape the pads quickly and hang them to dry. Some shrinkage may occur due to the natural materials. Thank you for your understanding.
