Lids don’t fit securely on a 16 oz bottle. When lifted by the cap it came off without unscrewing.

Cheap, ill fitting caps. they tighten and then pop a-loose. I would not trust these caps to secure any liquid in 16 oz bottles.

I bought these along with the 16 oz round trigger spray bottles from this company. The bottles are fine so far, but I dont like to store my product with the trigger sprayer, and wanted these replacement caps for storage. They leak and if you try to tighten to hard they hit a certain point and loosen back up. Would not recommend these caps.

I purchased glass jars with pump lids for my homemade joint/muscle pain reliever, but it is to thick and needs shaking, so these lids solved my problem.!
