I have a sentence structure like this:
There are two types of "something" - "item one" and "item two", - which differ significantly in "some features".
Is the use of commas and dashes here correct?
If you want to use the dashes, remove the comma. Other approaches include these. There are two types of "something" ( "item one" and "item two") which differ significantly in "some features".
