Purchased on Rakuten in May and July 2024. Shows signs of wear from multiple uses, but there are no noticeable stains. Washed with Arau Baby unscented detergent. Size: M: 6-8.5kg / 3-6 months Pattern: Lemon (mesh), Green (mesh) These were very useful! Babies tend to get hot, so mesh material is recommended from early spring onwards.
