I buy mine on Etsy from Indieowlcreations and I love them!!!
I also buy my caps from her cuz she sells them linerless and flattened(I ike mine flat) so altogether it saves me a ton of time!!
These are great and I have used them for almost a year now and have no complaints at all. I did however use a few suppliers before i found ones that I like at a decent price.
For those of you who need a way to save some time these drops are totally the way to go!
