Period-Plus Zero-Waste Thong - Menstrual Underwear
Le zero-waste menstrual thong is a menstrual panty of the "thong" type. The tanga resembles a traditional women's panty, but it can accommodate menstruation. Ideally, for light flow days.
Zero-waste menstrual thong: comfort and eco-friendliness
The zero-waste menstrual thong is an eco-friendly version of the traditional string bikini, specially designed for days with light menstrual flow. In addition to its refined design, it makes an environmental gesture by being made from fabric offcuts from our production of menstrual panties. Choosing this option means opting for a surprise pattern and color panty, with the option to share your preferences in the order comments (for example, "I like floral patterns" or "I prefer blue tones").
A sustainable, discreet thong
Le zero-waste menstrual thong features a natural-fiber lining, providing the feel of an integrated panty liner while remaining ultra-comfortable. Designed for optimal protection, it is slightly longer at the front and back to provide perfect coverage on light-flow days or as a complement to a menstrual cup.
Two color options are available:
- Natural : unbleached and undyed, ideal for sensitive skin and for those who want to visually monitor their flow.
- Black : for easier maintenance.
Uncompromising protection
Grâce à une fine couche 100% PUL, un tissu à la fois respirant et imperméable, votre tanga est à l'épreuve des fuites et reste confortable toute la journée.

Size and exchange:
Buying panties online isn't easy. You never know if the fit on
will be fine for us. I understand you.
To order the correct size, measure your hips above the buttocks,
using a measuring gallon that will be positioned so that it is parallel
on the floor. If you are between two sizes, choose the larger one.

If the panties still don't fit despite this precaution, they can be exchanged
according to the return and exchange policy and in compliance with all the
following conditions:
- The panties must not have been worn without another undergarment underneath during the fitting.
- It must not have been washed.
- She must be returned in the same condition as the panties were sent to you.
