Most like the ease of use of the cotton pads like Cullin posted. If you want to try some you local vape
shop will be glad to sell you some for an inflated price. About $5 for 3-4 sheets seems to be the going price for most vape shops. But it will last you a few weeks most likely.
Others buy organic cotton balls from Walgreens or I buy cotton salon coil from Sally Beauty supply. There is also Cotton Bacon not cheap which is good.
