You have purchased heirloom quality glass tree ornaments.  In order to care for and protect your treasures so they will last for years to come, please be mindful of the following suggestions.  

These Christmas glass ornaments should be cleaned with a soft, dry cloth to remove dust and fingerprints.  Avoid abrasive cleaners.

Hand painted glass ornaments should be wrapped individually in acid free tissue paper and packed securely in a box. 

Make sure not to place too many layers in a single box.  A single layer is ideal.

The box should be very sturdy and always be made of paper. 

Plastic bubble wrap and/or plastic storage containers do not allow the blown glass ornaments to have proper ventilation (particularly if stored in a warm place like an attic or in a humid place like a basement). Please remember to remove the ornaments from the packing box and bubble wrap after your order arrives.

Also be sure to take care to store your items in a safe, dry place away form fluorescent lights, water, sun, and other outside elements.

Finally, these heirloom glass Christmas ornaments are glass.  Do not drop them or knock them against each other or a hard surface.
