What are these and what are they for? The girl sitting across from me had them on all her fingers on both hands.
Answer: The items on her fingers appear to be finger protectors or orthotic finger splints. These are often used for medical or therapeutic reasons, such as:

• Preventing hyperextension (common in conditions like Ehlers-Danlos Syndrome, arthritis, or hypermobility disorders).
• Protecting healing injuries (like sprains or fractures).
• Providing support for repetitive strain injuries (common in musicians, typists, or people with tendonitis).
• Assisting with grip and function (for individuals with joint instability or weakness).

If she had them on all her fingers, it’s likely she has a condition that requires joint support or stabilization.
