• 【Self-designed with multiple functions】: It can measure the length and width of cracks and scratches, the diameter and area of points, and the angle of the measured object.
• 【Dual-Sided Laminated Wear】: Each card is designed with three layers—a double-sided wear-resistant protective layer and a middle printed layer. This design ensures that the numbers and patterns on the printed layer remain clear, preventing loss of precision due to wear and tear, thereby effectively extending the card's lifespan.
• Convenient to use:place the ruler on the crack, scratch, or point that needs to be measured, select the appropriate line width, point, or angle for comparison, and measure the width of the crack, scratch, point size, and angle.
• Convenient to carry and store: The size is only 80✖100mm, which can easily fit into pockets and wallets.
