( Q )

Will there be stains on my underwear?

( A )

Our absorbent underwear isn’t stain-proof, although the materials used in our absorbent gusset are largely stain-resistant. Plus, they’re lined in black to prevent stains from showing. To further prevent stains, follow our washing instructions.

( Q )

How many pairs of Thinx Teens do I need?

( A )

Purchasing one of our Fresh Start Period Kits is a great way to have multiple pairs of teen period underwear on hand, but some people start with just 1 pair and wash them throughout their cycle (daily). Ultimately, it’s up to you on how you want to use Thinx Teens — do what’s best for your lifestyle and unique flow.
