@**TD** Aesthetically, I like 1 and 3 the most, but having shadows printed doesn’t make as much sense when there will actually be light occlusion caused by the oppai.
For that reason alone, I think 2 is the best choice.

@**TD** so I would have to buy the popsicles, the board, and the skin all separately? Or the $7x has it all?

@**TD** Cool idea but it really depends on the texture on those covers. If they are high quality while being washable, there might be some interest in them. It also depends on future support as it seems weird that they are selling the oppai separated from the board for seemingly no reason. (More sizes down the road maybe?)

#1 is my cup of tea if I can only buy 1. Otherwise, #1 and #2.

Definitely a cool idea but unlike pillow covers, the usage is sort of lackluster and I don't think that people would often replace their mouse pad covers.

@**TD** 

The concept and interchangeable covers is kind of cool--it would be cool to see doujin artists get into creating covers and printing with some of the Japanese hobby printers like Shiromoufu or A&J or similar. However, the all-in price is just high enough to push it out of "fun, impulse buy" territory. If the oppai are reasonably large that portion isn't so bad, but the base and covers seem kind of high for what they are/the art on the covers.

That said, of the extant covers 2 is probably my favorite.

@**TD**  As awesome as this is, and I do love it, I could never actually buy it, because I could never use it. At this point in my life, I just don't have enough privacy to be able to have that on my desk. :D Although, if I could, it would be cover #1 or #4.

@**TD**  would be a tough decision between number 3 and 4. Older sister vs sweaty athlete

@**TD** Also comment and let us know which of the 4 covers would you choose.
