Can I build a custom bundle with different flows and styles?

Absolutely! At Louloucup, you can build your own custom box by mixing heavy-flow panties, lighter styles and even a period swimsuit. The more items you add, the lower the price per item!

How long can you wear a Louloucup panty?

You can wear it for up to 12 hours at a time. Our wicking fabrics trap flow and moisture instantly, which prevents odours. For extremely heavy bleeding (over 70 ml), we recommend having a spare pair or using a Louloucup in addition.

How do I care for my panties so they last a long time?

It’s easy: rinse it in cold water after wearing it, then machine-wash at 30°C (short cycle, no fabric softener). Finally, let it air-dry. Avoid the tumble dryer to preserve the performance of the technical fibres.
