～でできる

About

The ～でできる pattern is a combination of the で particle and する's potential form (できる). ～でできる is used to express what something is made from and tends to be used when the material is obvious or can be discerned easily.

The ～でできている pattern is also possible. Compared to ～でできる which focuses on potentiality, ～でできている places more emphasis on the end result. (Think "made from" (でできている) vs "can make from" (でできる)).
