This is a flyknit zipper that came with a baby bedding cover, specifically a sheet cover. Length: Approximately 105-106 cm My child has outgrown it, so I no longer need it. I repurposed the fabric into pillowcases, but the zipper is left over. I think it's a perfect size for those who make custom sheet covers or duvet covers for children. There were also some cover ties, so I'll include them as a bonus if you'd like. Baby bedding Nursery
