Lemon-patterned sleep sack. Easy to use with snap buttons. - Design: Lemon pattern - Material: Cotton (likely) - Fasteners: Snap buttons Size is not specified, but I think it can be used for children around 1-2 years old. Thin, so suitable for spring and summer. I purchased it online, but originally, one of the male snap buttons was missing. (Please check photo 4) There are no stains. Thank you for looking.
