This set will fit a preteen or a small teen or very small adult. The pom-pom is removable. I got this yarn from Temu, and it is a little bit thinner than a 4 weight, but thicker than a 3. The yarn is pretty soft, and I really liked working with it, but because it’s thinner it doesn’t stretch as far. The color is so pretty though! I’m pretty happy with this set!
