MN-120S Plastic Model Dedicated Nipper

Store the nipper in a dry place when not in use.
Wipe the nipper with a dry cloth after each use to remove moisture.
Apply a light coat of oil to the metal parts to prevent rust formation.

Ensure you are holding the nipper correctly and not applying excessive force.
Consider adding handle grips or using gloves to improve comfort.
If discomfort persists, you may need to choose a different size or style of nipper that better fits your hand.

Ensure the plastic being cut is within the capacity of the nipper.
Check for any nicks or damage on the cutting edges. If damaged, the nipper may need to be replaced.
Make sure the pivot joint is lubricated and operating smoothly.

Inspect the nipper before each use to ensure the cutting edges are sharp and free from damage, and that the handles and pivot joint are in good condition.
