Talking about weird cultural things. Pretty much every Spanish household has at least some of their drinking glasses made up of the glasses used by Nocilla (Spanish chocolate spread brand). https://dechocolate.net/wp-content/uploads/2013/08/nocilla.j...
Amora mustard glasses are famous as well. They are designed to be reused as table glasses and often have pictures on them so children love to get them. My son used to badger me to get all the Pokémon ones.
Yes I do recall but on the thin side iirc. Also worth mentioning SPC iirc jam that was sold in stores were great drink cups with a tight lid - I still use one every day and it's outlasted many other glass drink cups.
