These do not fit the 4 oz herbal tincture bottles I have, but do fit the 1 and 2 oz ones.

I was worried that these wouldn't fit my 4oz Boston glass bottles, but they do! They screw down tight and are leak proof. Originally I was worried about being the first to buy and review a product, but thankfully it worked out just fine :)I'd found a few 4oz bottles at Value Village and though I had the correct sized caps, but literally nothing fit (not even taking caps from stuff in the fridge!) and there was literally no help online telling me what size I needed to buy. Thankfully I deduced size 22 and then went shopping. Was really, REALLY glad these actually work!
