I adore these knobs!  The provided screws were too long for the existing knobs I had so I reused those from the original knobs.  They are quite heavy and very sparkly in person.  My intention was to change the hardware on my nightstands and dresser to make them seem closer to a match, despite being from different collections.  If youre unsure about these knobs, just order them!  You wont be sorry as the quality is great for the price.  The only annoying thing was ordering 20 and having them all individually packaged inside one large box, but I know thats to prevent damage in transit.
