These period emergency kits for are great for tweens/teens to discretely carry in their backpacks when they could be expecting their first period or just to keep on hand for the next one. The nylon zippered pouch is approx. 4.75" x 5.15" x 2" and includes a quality pair of black period panties (chose appropriate size) from The Period Company as well as an ultimate care kit that includes a regular flex foam pad with wings, panty liner, tampon, shout wipe, hand sanitizer wipe, wet wipe, midol and a period tracker. Hopefully being prepared will help her feel she can do it!
