Cultural Tip
In most Spanish‑speaking countries the word 'papelería' refers to a shop that sells school and office supplies, including rulers. Larger supermarkets and 'tiendas de conveniencia' also carry basic stationery. Remember that 'regla' can also mean 'rule' or 'law', so if you’re talking about legal matters you’ll need extra context to avoid confusion.
