Pros
- Includes two pillowcases with overlapping envelope closures rather than open-ended cases.
- Full elastic around the fitted sheet is intended to help keep it in place.
- California King size and claimed 18-inch pocket depth may suit buyers with deeper mattresses.
Cons
- The listing's care guidance is more restrictive than a simple machine-wash label suggests, so it may require more attention than standard bedding.
