I found that I disliked the feeling of the nail foils on the hearing aids – they were sparkly, so a bit scratchy on my delicate, sensitive princex skin. To remedy this, I simply applied plain stickers to my hearing aids. I’m kinda sorta in love. I also colored the tubing with Sharpies, which is a Thing I guess! I went with a neon pink sharpie, but it looks almost purple, yes?
