You see three items before you:
A wig that can become any colour/style and never frizzes/goes out of place.
A needle/thread that can match any fabric and easily creates seams that never rip (can be used in a machine too).
Contacts that match your prescription if you have one and can become any colour/size that never dry out so you could theoretically leave them in forever.
You can only take one. Which one do you take?
