If you have high returns, maybe try this solution for your eBay business

I bought the UV pens in the video from this seller. I negotiated down since I was buying 3 to $12, correction from the $10 I said in the video.

Bought these on Amazon on the 9th and they haven’t even shipped yet and have an expected delivery date of sometime late November. Cheaper, but waaaayyyy slow.
