JMU Orthodontic Neon Elastics 3/8 Inch Heavy 500 pack Intraoral Elastic Bands Latex Free Dental Rubber Bands Made in USA

I use these for my sleep retainer. Some of the bands are weak and break right away, but only about 3-4 per bag. Does the intended job.

Use for fly fishing and they are excellent

Found a different application, use them when building fishing rods to hold guides to rod, makes placement adjustable until final location is determined.

Although each ziplock bag did not have a tamper-proof, tear-off seal, they do seem actually new and unused, which is nice since they're designed to go in someone's mouth. Also, there were at least 100 in each bag, if not a few extra. They are not precision cut so they vary in thickness a bit, but the diameter seems consistent. They are not exactly like the orthdontist's but they're better than many others on this site.

I have been suffering for over a year from oral sores due to latex intolerance and orthodontic elastics. As a last ditch effort to fight off the painful condition, I purchased these. They are definitely not as strong or as durable as the latex ones I was provided by ortho (Smile Safari 3/16 heavy 6.5 oz) and I am able to snap these rather easily. They are far more comfortable to wear than the latex elastics, and while it may require a longer treatment using these weaker (though stated to be same strength) elastics, at least I’m not erupting in ulceration. I wish they were a bit stronger and more durable, but I will take what I can get at this point.
