Richard Z. ★★★★★

The texture is so ridiculously smooth that I actually sleep differently now, almost like my face glides on it instead of pressing into a pillow. My morning creases are definitely fainter, and my hair isn't a tangled mess either.

Ruby ★★★★★

My skin looks noticeably smoother after a week, and the envelope closure keeps the pillowcase snug all night. The silk is cool to the touch and I wake up with fewer crease lines on my cheeks.

Abigail R. ★★★★★

Woke up this morning and actually had to double-check my mirror because the usual crease lines on my cheek were barely there. The silk is smooth enough that my hair didn't tangle into a nest either. Worth every penny for how rested my skin looks now.
