To ensure the quality of your Merci chocolate remains optimal, follow these care tips:

1. **Storage**: Keep the Merci chocolate in a cool, dry place away from direct sunlight and heat sources. Ideally, store them in a pantry or cupboard.

2. **Temperature Control**: Avoid exposing the chocolates to extreme temperatures, as they can cause them to melt or lose their shape.

3. **Handling**: Handle the chocolates with care to prevent them from breaking or melting. Hold them gently and avoid squeezing or dropping them.

4. **Avoid Moisture**: Keep the chocolates away from moisture, as it can cause them to become sticky or develop a white film (known as chocolate bloom).

5. **Consumption**: Enjoy the Merci chocolates within a reasonable timeframe to experience them at their best. While they have a long shelf life, fresher chocolates tend to have better flavor and texture.

By following these care tips, you can ensure that your Merci chocolates remain delicious and enjoyable for as long as possible.
