I ordered a silk pillowcase from the brand "Sufella" but the size wasn't suitable for my pillow, and they don't offer exchanges or returns. It's still new, unused, in its original box and bag, and would make a great gift. I bought it for 280 and I'm selling it to whoever is serious for a price that suits them.
