Review on Premium Toddler / Travel Pillow Protector for 13x18 and 14x19 Pillows - Ultimate Sleep Comfort for Your Little One (1-Pack) by Jessica Ward

First of all I didn't know they were made of polyurethane. Folding pillowcases properly is "difficult" - they swell up as air gets in - whether the zipper is open or closed. Also IMHO, low quality flash. They're thin, plastic, and have tiny handles that don't make them easy to use. I'll admit I'm a zipper snob, because zippers can mean the difference between a product that's a pleasure to use and a product that turns into a nightmare. I'm afraid they belong to the second category. I usually check the quality of a zipper very carefully before I buy it. Forgot this time - live and learn. Unfortunately, the terrycloth material gets caught on the narrow plastic zipper when opening or closing, so you have to be very careful. Not cool. However, it would be great if the zippers were wider, metallic and with more pull; Real cotton terry fabric exterior is soft. Not recommended if you don't mind messing around with tricky zippers all the time.
