The staples are fine but the packaging could be improved. If you're not careful all the staples could slide out while carrying the box.

Light duty 5/16” staples

These are required for the Mastercraft light duty stapler. Perfect for light duty tacking where regular staples are overkill. Note that standard staples will NOT work in the light duty stapler
