I've used a few colors just to try them out, but not to the point of scraping them off. There are some stains around the case while it was stored at home. Normally it takes about 514 days to arrive, but now there are delays due to the effects of reduced air traffic, and it may take up to a month to arrive. International Buyers - Please Note.
