the young bridget jones: firmoo
They arrive with the cloth (which has quite strong plastic smell and washing it will be required), sturdy case and screwdriver! Mini screwdriver, I was so impressed because I have seen many people who had broken their glasses ended up buying new pair or taping it up. With Firmoo, you have a mini screwdriver accessible in your case! :-) It will be great with tightening your loose glasses too.
