They were easy to apply and the colors matched perfectly. It took me a while to figure out what order I want the buttons in, but so far I like it. The package contains illustrated and written instructions (not in English). Luckily, the photos are easy to understand. When sticking the sticker, be sure to press down the edges before lifting the paper to make sure it sticks well. 3 additional rows of stickers are included in the pack (enough to move both sets of buttons once and then another set of 4). The Joy Cons feel great and I look forward to playing with them in ACNH.
