You are asking about combining several elements and giving a recommendation and that's not a thing. Reasons for fail:

1. Price. We have no idea of your budget.
2. Use case. Are these for use at your job in the smelting plant or as a Les Clefs d'Or Concierge at a five star hotel?
3. Ethical is not a simple term. Sustainable materials. Sustainable employee wages. Fair Trade. Certified B Corporation. Woman owned business in Djibouti. We have no idea of what your idea of ethical is.
