All mine 18mo dinosaur onsie 100% cotton, long sleeves

18mo, great condition but there is a mark above the blue dino on the neck (second to last photo). Might come out with a washing, but don't want to wash as your little one might be allergic. This was my son's and had been in storage for about 17 years. Smoke free home. Pet friendly (now) but always stored separate. All mine brand
