Does this fit standard rectangular pillows?

No. This pillowcase measures 80×80 cm and is designed for European square pillow inserts. Standard rectangular pillows will not fit properly in this square format.

Can I wash this in a washing machine?

Yes, the pillowcase is machine washable. Follow the care instructions included with the product to maintain the silk fabric properly.

What is the zipper placement on this pillowcase?

The invisible zipper runs along one seam and is designed to remain hidden when the pillowcase is in use, so no hardware is visible from the outside.

How does silk reduce sleep creases compared to cotton?

Silk creates less friction against skin than cotton, allowing your face to glide across the surface as you move during sleep rather than bunching or pressing into the fabric.

Silk Pillowcase for European Square Pillows with Invisible Zipper

Most silk pillowcases come in standard rectangular sizes, leaving anyone with European square pillows to improvise with cases that bunch or sag. This one is cut to the 80×80 cm dimension that continental and European square inserts actually measure, so the fabric lies taut without excess material gathering at the edges. If you already own square pillows or you're building a bed setup around that format, this gives you the friction-reducing benefits of mulberry silk without forcing you to replace your inserts or settle for an ill-fitting case.

Good gift when

People who already use European square pillows and want a silk option
Those concerned about overnight friction affecting skin texture or hair
Anyone replacing cotton pillowcases to reduce sleep creases
Sleepers who prefer the aesthetic of a continental pillow setup

The details

This square pillowcase uses mulberry silk in the 80×80 cm format common to European and continental bedding. The fabric lies flat against your face and hair as you move during the night, reducing the friction that cotton creates between skin and pillow.

An invisible zipper runs along one seam, keeping the pillow insert tucked inside without exposed hardware. The closure stays hidden when the pillowcase is on the bed, maintaining a smooth appearance on all visible sides.

The silk surface has been dermatologist recommended for those concerned about compression marks and texture from overnight contact with fabric. In user testing, more than 95 percent of participants reported that creases and lines from sleeping were reduced and less visible after switching to this material.

Machine washing is supported, with specific care instructions included. The pillowcase measures 31 inches by 31 inches, fitting standard European square pillow inserts. One pillowcase ships per order.

This format works when you already own square pillows or prefer the symmetry of a continental pillow arrangement. The mulberry silk construction offers the same smooth texture found in other silk bedding, scaled to the larger square dimension.
