I just got these here:

It's a pack of 10 for only $5.67 shipped. It took 2.5/3 weeks to come from China, but I didn't mind waiting for the price.

You can get them as a 10 pack off Amazon here: http://www.amazon.com/Acupressure-Massage-Rings-Chinese-Medicine-10pcs/dp/B00DN0KZLI/ref=sr_1_2?s=hpc&ie=UTF8&qid=1426912484&sr=1-2&keywords=acupressure+massage+ring

I have also owned a spiky, and can't tell a difference in quality. Get the 10 pack.
