Well for a collector will be fine to keep them but you want to use them again and again.. I leave it up to you....I don't see no instructions about not to reuse them. If you read up there where it says in CATEGORY it says collectibles...
well, probably I did not answer your question....let me share some info regarding the flatware. THE FLATWARE IS THICK IS NOT LIke the material of a regular plastic spoon when you eat a piece of cake....the flatware material can last longer because of the thickness.
