This will be brief!
The thing that I hate about some cotton rounds is that the fibers break lose from the round. I think that this comparison shows why.
The top cotton round is a Swisper. Granted, you can get a great deal when you purchase them from Costco BUT, look at the texture.
The bottom cotton round is from Ulta. Yes, they are like $2.49/package but if you want something that holds up better, I think it is a better deal.
I will continue to purchase Ulta Cotton Rounds.
