Width: Approximately 15-16 cm Height: Approximately 10-11 cm Neck circumference: Approximately 24-27 cm (Please note that there may be slight variations.) Adjustable with two snap buttons! This is a four-layer gauze bib made by combining two layers of double gauze. It's thin, so it's perfect for the hot season, and it won't be bulky even with thick winter clothes. It also dries easily. It's easy for a sitting baby to see their hands while holding toys. I make each item with care, but as a handmade item by an amateur, there may be some imperfections like slight distortions, and it is not as perfect as a mass-produced product. Please understand that there may be some wrinkles. Since it is gauze fabric, hand washing is recommended. Please avoid using a dryer. * Those who purchase immediately will be given priority, even during comment exchanges. * If I am slow to respond, I may cancel the sale. * I do not offer reserved listings.
