Two twin sheet sets by Pottery Barn in 100% linen extra large in a pale gray color (looks beige in some photos).

The two top sheets size XL Twin are 105 in x 74 in (one label squished)

Two bottom sheets with elastic XL Twin are 80 in x 39 in (with "top of sheet" and "bottom of sheet" labels)

Two pillowcases KING size are 40 in x 20 in

Machine Wash Cold Gentle Cycle.  Only non-chlorine bleach when needed.  Tumble Dry Low.  Warm Iron as Needed.  Made in China.

NOTE:  

Date/Lot/Batch information on a tiny tag on both top sheets match each other (3/2022 Lot 2022 Batch 04).  Pillowcases also match each other (9/2021 Lot 2021 Batch 10), and both bottom sheets match (12/2021 Lot 2022 Batch 01); but as a set, none are the same dates/lots/batch numbers -- this is AS FOUND.  Nevertheless, I can't see any difference in the shades of pale gray in either set.
