Hey Roopa,
I know of a very good wholesaler of Rakhis. Its S2 creations. They are originally saree and other Indian dress material manufacturers and have some of the best designers in their company. They also make Rakhis during the season and export these high quality Rakhis to Europe, America and other parts of India. They have a website too
sareez.com but this website only shows sarees and dress materials for now. But you can drop them a query and they would definitely get back to you with pictures and details of their Rakhis. You can also contact them at:
8/1, Lal Bazaar Street,
Bikaner Building, Room No. 5B
3rd Floor, Kolkata 700001.
West Bengal
India.
Phone: 09836198482
Hope this helps you too.
Regards,
Bids
