Non-traditional use
I am a special education teacher. I am using these O rings because the occupational therapist for my students made "weighted" pencils for my students by taking an O ring, sliding it on the eraser end of a pencil, sliding 2 3/8-16 Hex Nuts on the pencil, and then securing them there with a second O ring. My students LOVED the weighted pencil. It is fulfilling multiple educational purposes. Thank you for selling the O rings in an affordable bulk package. You have made teachers and students very happy!
