We often have LS bell hammers in our hands, but we do not have any rough hands or other symptoms.
However, it cannot be said that there will be no impact on the customer's constitution.
If you feel uncomfortable, wear gloves, etc. so that you do not touch it, and if it gets on your skin, wash your hands thoroughly.
In addition, if the product is swallowed, there is an item for first-aid measures on the product. Follow the instructions there.
