I had those in the first link, too. They worked fine, but are a bit on the small side and faded before very long. I now have these https://www.amazon.com/Keyboard-Stickers-Fluorescent-Conversion-Keyboards/dp/B07BMKDFVW and like them much better. (There is an error on the ㅈ / ㅈㅈ key--the single and double are reversed on the sticker, but it doesn't affect anything.)
