Large and thin
Size: Queen (Pack of 2)
This pillow is large and relatively thin, and it's not soft to the touch; it has a granular texture inside, which I prefer. However, it's too high and too soft for me.

Wonderfully Surprised
Was expecting the worst after receiving another product from China before this, but this pillow is all quality!
Filling, material, loft and the black piping were excellent quality. Pillow is ready to go after 15 minutes. Packaging very nice and shipping on time. I'd definitely purchase from this seller again!
