The Print! ♀️✨Mermaid Fantasy 🌊🧜

This design is dreamy, enchanting, and full of magical charm. Shimmering mermaid scales in pastel turquoise, pinks, and purples cascade across the fabric, creating an iridescent, metallic effect that feels like actual fish scales. A hidden fishtail with the Justine logo adds a whimsical, playful touch. Perfect for fantasy lovers, pastel enthusiasts, sea lovers, or anyone who appreciates beauty, sparkle, and a touch of magic. Soft, mesmerizing, and utterly enchanting. 🌊🧜♀️✨

How does period wear work exactly?
Period wear is designed with special absorbent and leak-proof layers that provide protection and comfort during your period. The fabric technology wicks away moisture, absorbs flow, and prevents leaks, keeping you dry and confident. It's reusable and easy to care for—just wear, wash, and repeat.
How do I care for period wear?
Caring for your period wear is simple and ensures it lasts for years—up to three or more! After use, rinse them with cold water until the water runs clear. You can then hand wash or machine wash them on a gentle cycle using mild detergent. Avoid using harsh chemicals, bleach, or fabric softeners, as they can damage the fabric's technology. Most importantly, never use a dryer—air drying is the best way to keep your period wear in top condition. With the right care, your period wear will stay as good as new.
