Input: The big minus for me was that these very thin stickers were on a card that didn't want to let go of them. The first few I applied took several tries to remove with a reasonable length fingernail.  After I'd finished the top row, I got the clever idea to peel away the flash that surrounded the stickers, exposing the edges. Then I could fold the card back and easily get the individual stickers loose. I did take care not to peel so far that I couldn't match the sticker to the appropriate letter--the stickers are clear except for the Hiragana character--and I got through the rest of the task in reasonably short order.  Note that these stickers are small and meant to fit on the crown of a standard key. I expect it should be fairly easy to line them up and then simply tap down with a fingertip.  I say I \\"expect\\" that because I actually applied it to an [[ASIN:B000V07N9U Apple Aluminum Keyboard]], which has key-tops much larger than a standard keyboard. The stickers did fit fairly easily, though I occasionally needed to adjust the placement after putting it down, and I frequently ended up with fingerprints on the adhesive.  Overall, though, now that they're in place, they do what I wanted them to do, which is simply to show me what key to hit when typing Hiragana.  It should be noted that these keys produce a layout for Kana typing, which is much less common than Romaji typing, which most operating systems default to when you set them to type in a Japanese character set. For the Mac, it's fairly simple to change to kana typing...as long as you know where to find the right preferences panel.

A bit more laborious than it needs to be, but handy when you're done with set-up.
