Where to buy good quality plain glass magnets in bulk outside US for my art project?

I have found a US company that supplies the above mentioned only to its region.

I would like to explore making glass magnets with my family, students and churchmates.I believe it could really make a great hobby to some, to give away or sell as inspirational gift, etc.

I need at least 100 pieces….

Please advise. Thank you:)

1)By the way, any tips of making, protecting and marketing them?
2)What’re “the best ways” to display them; first for gift and second for marketing purposes?
