We will be adding the ability to add bullets to text in ONTRApages soon! Until that time, you can use this technique.
Use the Product Details block, and stack them up on the ONTRApage. Click "Next" and "Previous" to see the variations of the block; you can also do 2x2 or 3x3 across:
It starts like this:

Then, if you'd like, you can make it single-column by hiding or deleting one of the 'items' in that block.
Then stack them up by copying the block...

Change the images to check marks, reduce or style the text, etc. to get the effect you want!
