Review on Imperial Measuring Pieces Feeler - Enhanced Precision and Markings! by Christopher Wiggins

Engraving/painting aside they served their purpose although shorter than I expected. Price was right and shipping was quick... I'm not sure what is the reason for the two different details on the blades but they are both 0.10mm to 0.13mm thick I can't find 0.11mm or 0.12mm in any of my kits Feeler gauge is included. They're oil coated "to prevent rust" according to the manufacturer, but they also claim they're stainless steel. Get what you pay for, that's no lie. :)
