What if you put a picture of each ornament in the pocket - and keep the ornaments at your home? I don't think they have much room for "stuff"
What about little things she might need? Lip balm, nail clippers, toothbrush, hand sanitizer, wet wipes, cell phone minutes, batteries, life saver white mints, feminine hygiene products - when they are gone, they are gone - no need to worry about breakage or carrying around.
I don't know what is allowable for mailing/shipping - might need to check with the post office for that.
