Effective alignment pins, but cheaper elsewhere

These alignment pins work as expected and are especially useful for lining up old flanges that are not correctly two-holed with new flanges, including after separating and rebolting. They are frequently borrowed by coworkers. However, the same pins can be found on the manufacturer's website for about twenty dollars less per pin, making this purchase forty dollars more expensive. The package also included a can holder with the manufacturer's website printed on it. Buying directly from the manufacturer is recommended for lower prices across all sizes checked.

Pros
  • + works as expected
  • + effective for aligning old flanges
  • + useful after separating and rebolting
  • + coworkers frequently borrow them
Cons
  • − overpriced compared to manufacturer's website
  • − paid forty dollars more
  • − package included unexpected promotional item
