Here is a lot of two knit collars in white trimmed with green, yellow, and blue stripes. These are made for child-size clothing.
The collars are not in packages and I do not know the fabric content, but I am guessing they are a combination of cotton and polyester. They are stretchy with a good weight.
MEASUREMENTS: 2.75 inches wide and 10 inches length
Both of the collars are in perfect condition, from my smoke-free and pet-free home. They have been stored in a closet, away from sunlight, and in an air-conditioned home.
