50 characters is plenty for a title. It is not meant to be multiple lines long. With very few exceptions anything beyond that is stuff that should be in bullet points or the product description.
I already avoid buying items from sellers that keyword spam their title as that is a good sign that it is a piece of private label Chinese junk being listed by someone that spent too much time watching Amazon gurus on YouTube and follow their bad advice. It is ridiculous. You see stuff like “Cute baby infant boy girl present gift child birthday baby shower soft towel gift set for infant boy or girl”.
