What to know before buying

Listing details to confirm

The listing calls this 9-in-1 but names fewer than nine distinct functions when the flat and Phillips screwdriver tips are counted separately. Treat the tool count as a listing claim, not a precise inventory of independently verified functions. The feature text claims three replacement refills and three replacement batteries, while the explicit included-components list names only a pen. Check the selected listing for these extras.
