I have used these before and that is why I purchased them again.

This pillow protector looks really good quality, I would have been really happy with it, but I'm disappointed by the sizing. It said 'standard' and I checked my pillow that I have a standard pillow. But I didn't find the actual measurement information until too late, and the pillow protector is 5cms too long and 5cms too wide for my pillow so it's basically not usable. I'll have to find another one somewhere else.
