2WT and 2WR have the best feel. Im actually surprise that webby has a option for 2WT.
most knockoffs are made with peachskin polyester by default, I can show some comparison photos of my Kotonoha daki, the bootleg was one of my earliest daki when a stupid and naive kid a few years back.
ORIGINAL
BOOTLEG/KNOCKOFF
As you can see, aside from the print quality, the bootleg creases ver easily, note that I always fold my dakimakura, you will notice that there's barely any creasing on the original.
Off topic: I just changed to my new bed, a gift from my grandmother, it has a amazingly cool large bedframe that doubles up as a storage box when you lift the top of the frame. Now I shifted about half of my daki collection inside.
Now I got more space for dakis!!!
