I was mostly joking though I do eventually want to visit Japan. Many years from now, if/when I actually do I'll probably spend hours looking for this comment for the name you just provided. ;)

Yeah, I looked again and didn't realize that it was for a 10.5 inch device, not 10.5 inches wide itself. It's actually 30cm which is too large for my purposes.

I came across this one that I might try but it's a little thin, especially considering the double layer: https://smile.amazon.com/gp/product/B016HRHGIS

For $20 I won't feel that bad if it doesn't work out.
