Tampax Tampons For Vending Dispenser In Vending Tubes - Case Of 500 - Hospeco T500

what are the dimensions of each indvidual tampon

It says this is for 7 cs and each cs has 500 tampons. so does this purchase of 7cs include 3,500 tampons?

I really want these tampons but not 500 units worth. Are these available in smaller batches? (multiples of 20 or 50)

Please help me understand: 500 tampons in the 7 units or 7 units of 500 each?
