This is a drool cover that can be used with a baby carrier. It's reversible! Both sides use double gauze, making it a gentle material for baby's skin. A domit core is sandwiched inside, making it fluffy and absorbent! The size is approximately 14cm x 20cm. (I myself use an Ergobaby Omni Breeze.) If you have any questions, please inquire! ⚠︎ It is also listed on Minne, and there may be cases where we cannot meet your request due to limited stock, so please understand. ⚠︎ This is a handmade item by an amateur, so please understand that there may be some distortion, wrinkles, misalignment, and loose threads. ⚠︎ Please refrain from purchasing if you are looking for a perfect product.
