I received a decent sized sample (there were 4) in the mail, but the sender was unknown. I'm not certain I understand how to assess that one pantyliner is better than another, but there wasn't a plastic-y top that made you feel uncomfortable, they were individually wrapped so you could carry in your purse, and the liner stayed in place. I'm not certain this sampling made me a fan for life. I suspect I'll still buy whatever brand that is one sale when I need these next. although there was a coupon attached that might help.
