Do You Think That The Tiffany Co. Keys Are Good Gifts? Best Answer 10 Points!!?

Well it’s my sisters birthday next week and for our birthdays our relatives put a collection surprise on us. Since the Tiffany Co. Keys came out, each relative of our is buying her a key.
She got this one from our Aunt:http://www.tiffany.ca/Keys/TiffanyKeys.a…
(I know its expensive but our aunt can go crazy while shopping!)
Our mom gave her this one:http://www.tiffany.ca/Keys/TiffanyKeys.a…
and we got her WAYYYY more, but anyways, its family tradition that w each buy one diffrent one from the collection and I was thinking of giving her the simple ong as she has too many fancy keys already:http://www.tiffany.ca/Keys/TiffanyKeys.a…
What do you think about the one im getting her? Do you think Im acting a bit cheap or do you think its an okay one becuase I dont want to spend thousands of dollars, i just want it to be memerable. It has the Tiffany Blue Heart on it too!
Tell me what you think!!!
