Yes, most permanent markers are designed to be waterproof, meaning that they will not dissolve or run when exposed to water. This is because permanent markers contain ink that is designed to adhere to surfaces and resist water and other types of moisture.
Permanent markers are commonly used to label or mark items that will be exposed to water or other types of moisture, such as plastic containers, water bottles, and outdoor equipment. However, it's important to note that the ink in permanent markers can fade or deteriorate over time when exposed to UV light, heat, or other environmental factors.
Additionally, while permanent markers are resistant to water, they may not be resistant to other types of solvents or chemicals. Certain chemicals or cleaning products may cause the ink to dissolve or smudge, so it's important to use caution when using permanent markers around other types of chemicals.
