Good quality keycaps. These caps really are beautiful. My only complaint is that there wasn't a blank or FN cap in addition to the additional win cap. Seems like an odd choice to include two wins when FN keys are so common these days. There were a couple of Tai Hao branded caps that apparently come with all Tai Hao sets but, not my cup of tea. I wanted something more professional and less gamery as these are for a keyboard for the office.

Notes and observations:
There were some small imperfections on a few keys but they were all on the sides and not easily noticeable.
The printing is flawless.
The caps are a bit tighter on the switch, slightly harder to remove, than the manufacturers caps. (I used these on a Redragon K551-N)
They are also slightly wider than the stock caps.
They have a rather hard edge (not rounded) to them, especially noticeable when using the spacebar.
