Precision Engineering & Anatomical Accuracy

As seen in our high-definition product video, these capsules feature a dual-ring Snap-Lock system. This ensures:

  • Zero Leakage: Secure closure prevents fine powders from escaping.

  • Mechanical Integrity: Precise 2–3mm locking depth for a satisfying, secure "click."

  • Visible Purity: Available in both translucent and solid colors for easy content identification while maintaining a premium, holistic look.  


STORAGE
To ensure the technical precision and Snap-Lock integrity of your capsules remains perfect, please follow these storage guidelines once your package arrives:

1. Temperature Control: Keep capsules stored between 15°C and 25°C (59°F–77°F). Exposure to high heat can cause the gelatin to soften or become misshapen.
2. Humidity Management: Maintain a relative humidity between 35% and 65%. If the environment is too dry, capsules can become brittle; if too humid, they may become sticky.
3. Keep Sealed: Always keep the capsules in their original airtight packaging when not in use to protect them from environmental moisture.
4. Out of Direct Sunlight: Store in a dark or shaded area. Our translucent red capsules are designed for aesthetic brilliance, but prolonged UV exposure can affect the gelatin's color and stability.

By following these simple steps, you will ensure a smooth, professional filling experience every time you use your CapsuleUSA products.
