Let’s talk care instructions for your period-proof undies. It’s as easy as pie—promise!

Wash with Love: Pop those undies in the machine on a gentle cycle, max 40°C, with a mild detergent. Hang ‘em up to dry—no tumble dryers, please! And steer clear of bleach to keep those colours poppin’!

Made with the good stuff: 95% Organic Cotton for that dreamy softness, plus 5% Elastane for the perfect stretch. The gusset lining? Yep, you guessed it—same soft Organic Cotton blend. And that leak-proof gusset? It’s 100% Microfibre with TPU magic.

Safe and Sound: Rest easy knowing our undies have no added PFAS and have been tested for all the yucky stuff. They’re certified according to STANDARD 100 by OEKO-TEX®, so you can rock them worry-free!
