Reddit mentions of AJ Dakimakura Body Pillow (63cm x 43cm x 12cm, MH2000, High Class)

So I've got two questions:

1. I know Shamoe sells mostly bootleg, but I did notice that they had some interesting bed sheets like this: https://item.taobao.com/item.htm?spm=a1z10.1-c.w8995098-11706158877.7.FsSRoR&id=523276484792
   
   My question here would then be, where to find legit bed sheets similar like those?
   
   As well as the question if that bed sheet which also has a dakimakura side here: https://item.taobao.com/item.htm?spm=a1z10.1-c.w8061016-10551194168.5.dFrHB5&id=523282727549
   
   is actually an original design from them or that it's stolen?
   
   
2. A recent post on this post spiked my interest with that A&J also sold normal sized pillows like the MH2000 (http://www.amazon.co.jp/%E6%9E%95%E6%9C%AC%E4%BD%93-A-J%E3%82%AA%E3%83%AA%E3%82%B8%E3%83%8A%E3%83%AB-MH2000-%E3%83%8F%E3%82%A4%E3%82%AF%E3%83%A9%E3%82%B9/dp/B00M9UCKQQ%3FSubscriptionId%3DAKIAJ3AS5HF6GECWRENQ%26tag%3DcLhaSxtp-22%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3DB00M9UCKQQ)
   
   Now the question here is, I imagine that that pillow is similar or close to the feel/materials used for the DHR6000?
   
   And with that said, does anyone know where I would perhaps find 2WT covers for the mentioned pillow (which is W63cm×H43cm).
   
   Thanks for any information in advance.

• Fishers Finery 100% Pure Silk pillowcase (Since it didn't look like A&J sold a pillow cover for the MH2000)
