Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Services ( Service_Type_Code VARCHAR, Product_Price INTEGER )
TABLE: CREATE TABLE Ref_Service_Types ( Service_Type_Description VARCHAR, Service_Type_Code VARCHAR )

### Question ###
What are the descriptions of the service types with product price above 100?

### Accurate SQL ###

SELECT T1.Service_Type_Description FROM Ref_Service_Types AS T1 JOIN Services AS T2 ON T1.Service_Type_Code = T2.Service_Type_Code WHERE T2.Product_Price > 100
