This little lady is quite frustrated by losing her freedom. But she is in a jar now and letting her out could be hazardous to your health. Best to just enjoy her beauty through the glass.
Her environment is specially tailored to her needs, including her favorite kind of moss for sleeping and holes for air. She can live happily (once she gets over being angry) in this jar for many years to come.
Pickled fairies are preserved carefully so as not to harm the fairy in any way. Because of the special preservatives used to save the fairy they can be expected to live in their jars for much longer than any fresh fairy would live. There is a drawback however, pickled fairies are in a trance like state and thus less entertaining to keep on your shelf.
