What can I say. Exactly as advertised, quite large enough to handle the king pillow as ordered. The zipper is soft and small thus will not be awful to roll onto. Best of all the pillow protectors are thick enough to be sure to handle allergens and not 'crinkly" nor 'crunchy'. Quiet, sturdy, soft, but not slippery. Have not washed them, but put out in sunshine before use to sanitize after opening the secure packaging.
