No fluff to fill
Style: Medium/Firm, Size: Queen
Arrives vacuum packed; not a problem with that; however, a week after opening the pillows are still flat. I thought they might still work for my pillow shams - not what they were bought for, but they didn’t fill out the shams either. Sad as I really like Serra brand normally.
