This is my second order - so I now have 4 pillowcases. They are excellent. I have 2 and help with hair frizz (a lot) and my son has 2 and believes helps with his skin. I also have 2 from Blissy - these are almost identical but not as big so my pillows are harder. They are also more expensive (USA). Definitely recommend silkpillowcases.co.uk
