These are beautiful knobs, but I wish they were easier to install. Unlike most cabinet knobs that screw through the cabinet and Into the knob, these knobs have an attached screw. This is explained in the description, but they say they are easy to install and they are not, unless you want a big screw sticking into your cabinet or drawer that will snag everything. You will need a bolt cutter and a metal file, plus some skill and time to cut each bolt and file down the rough edges.
