White ceramic knobs (Central Crouch End N8)

3cm W x 2cm D. Suitable for drawers, cupboards etc. Not sure what size screw/bolt they need.
23 of them altogether. 14 ARE IN VERY GOOD CONDITION, 7 have small chips in the collar, and 2 have a slightly larger chip. Photo shows the chipped ones in front (sadly dropped on hard tiles last week!) If the ones with a chip are rotated so it's below or above depending on the angle they're viewed from, it's likely to be unnoticeable.
