This is a First Rate oral sponge. They are star-shaped and slightly smaller, so I think they are particularly suited for the care of women and those who have difficulty opening their mouths. That's just my subjective opinion. The product is a set of 2 unopened cases, totaling 100 sponges. If you'd like to open them, I can also include 10 extra sponges as a bonus, so please comment when purchasing. Please note that shipping will be done in a simple manner. Please consider this only if you understand and accept this.
