You can try using Fengyoujing. Generally speaking, it can be removed.

For the annoying small price tags on ordinary plastic products, I have a little trick to get rid of them. That is to use a hair dryer to blow on them for about 3 minutes, until the tags soften and become It's in liquid form and can be removed with just one tap without leaving an annoying sticky patch.

Hope this will be helpful, good luck
