I bought this product because I heard it was good for ear stretching and I was very disappointed because it worked for me just didn't work. Even when I put it on the plug I have to replace the tape almost every few days because it's all tangled and gross. I went back to duct tape because it's stronger and I can peel it off very easily for a better stretch. Just my experience. Also for reference, my ears are 25mm to 28mm.
