This is a neck cooler made of towel fabric. I tried it once, but it was too tight around my neck, so I'm selling it. You put a cold pack in the pocket in photo 6 to use it. I haven't used it much, but there is some fuzzing due to the Velcro (photos 4, 5, and 7), so I've marked it as having scratches and dirt, but there is no actual dirt. It's about 40cm long as shown in photo 2. The cold pack pocket is about 6cm by about 17cm. Please note that these measurements are approximate. Cold packs are not included. Would this be suitable for a child? Please refrain from purchasing if you are concerned about it being stored at home. Thank you.
