Better case for sleep mask
 

Hi. I am seeking a better travel pouch for this sleep mask:

For the past 10 years I've used a gallon size Hefty slider freezer bag when traveling with this sleep mask in my pack, to keep it from getting dirty.

I am seeking something better-sized, which doesn't collect air/puff up like the current plastic bag, and is more pleasant to use. Somewhat washable would be a plus.

I checked Tom Bihn as I've been very happy with their pouches, but they don't appear to have anything with the proper dimensions.

I am seeking a flat pouch somewhere in the range of 25cm x 8cm. Slightly larger or smaller should be fine. Tom Bihn or similar level of build quality and smooth zipper action (if applicable) strongly preferred.

I tend to pop into Muji when looking for a pouch to hold something. Found a perfect smaller one there that holds my phone, with a place on the outside for my earbuds and slot inside for my ThinOptics.
