What to know before buying

Listing details to confirm

The listing gives inconsistent size information: the title says 1 x 1 cm, the description lists 10 mm and 20 mm, and the included-sheet breakdown totals 300 pieces across 6 x 10 cm, 5 x 10 cm and 5 x 5 cm sheets. Confirm the selected listing's actual dimensions and contents before ordering. Adhesion and magnetic holding strength are not quantified.
