I'm not sure how these ever got slapped with an 'Original price of $346.99' price tag. Thankfully I only paid $47.00.
The packaging alone was a 'red flag'. So generic looking and had I paid the full price, I would've promptly returned without even opening them up.
That being said, they smelled like they definitely were manufactured in India, but after a washing, which I hope everyone would do to a new sheet set, they seem to be well made and of good proportions for a deep mattress and box-spring. I'm not sure about the "1,000 thread count", but they're soft enough.
My tip to Wayfair: Suggest the vendor redo/update their packaging, it looks like something found at a dollar store.
My tip to prospective buyers: Look at some of Wayfair's other offerings first, don't just see the 'Original' vs. 'Sale price'.
