To preserve the quality of your 250 grams of mixed Patchi chocolates, consider the following care instructions:

1. **Storage**: Store the Patchi chocolates in a cool, dry place away from direct sunlight and heat sources. Excessive heat can cause the chocolates to melt or lose their shape.

2. **Avoid Moisture**: Keep the chocolates away from moisture and humidity, as they can cause the chocolates to become sticky or develop a white film known as "bloom."

3. **Handling**: Handle the chocolates gently to avoid damaging their delicate shapes and decorations. Use clean hands or utensils when handling them to prevent contamination.

4. **Consumption**: Enjoy the Patchi chocolates within a reasonable time frame to experience their freshness and flavor at their best. While they have a relatively long shelf life, consuming them sooner rather than later is recommended.

5. **Gift Wrapping**: If giving the chocolates as a gift, ensure they are properly wrapped and protected during transport to maintain their appearance and quality.

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