Price is for 1 beadable, add-a-bead, DIY novelty pizza cutter - great instant gift. The beadable bar portion is 2.2mm so any beads you put on must be at least 2.3mm>. We do offer a lot of larger hole beads, in other listings, that will fit this bar fine. This comes with a blue film on the stainless steel pizza wheel (to protect it in shipping) & you just need to remove. To use, unscrew the end of the pizza cutter exposing the round metal bar > add beads > screw end back up. The photo is enlarged to show detail.
There are plenty of free online measurement converters should you need help
