■ Westy Basic Color Collar Cover (830750) ■ Size: 150 x 50cm ■ Composition: 100% cotton ■ Color: White ■ Made in Japan This is a collar cover specifically designed to completely cover the top part of a duvet cover that faces your face. The collar area tends to get dirty more easily than other parts. It's a waste to wash or discard the entire cover just because this part is dirty, even though the rest is clean... This solves that problem! With this cover, you don't have to wash the entire duvet cover. You can simply remove the collar cover, wash it quickly, and put it back on! It's a very convenient cleaning item. It has no zippers or buttons, and can be attached with just elastic, making it easy to put on and take off.
