PL/SQL :: Retrieve Item With None Of Its Char Values As Null?

I have a table something as below

Things_t
Things Characteristic Char Value
Item 1 Colour Red
Item 1 Packaging
Item 2 Shape Square
Item 2 Brand Spunk

Now i want to reterive an item with none of its char values as Null. Using the query “ select distinct things from things_t where char value is Null ” will fetch the item 1 also together with item 2. i want to fetch a record from thing for which none of the char values are Null such as Item 2.
