Does anyone know approximately how many pearls come in a 4oz bottle of 4mm sugar pearls? I need about 500 pearls and need to know how many bottles, or bags to purchase. Thanks in advance!

Hmmmmm... I just looked at my 4oz bottle of 6mm pearls, and there are at least 600, so you should have ample 4mm ones in 4oz. But, they aren't that expensive, and if you are as fumble-fingered as I am, a spare bottle isn't a bad idea . You can always use them later - they keep forever.
