Child-resistant dropper cap for 60 mL bottles. 
This cap only fits 60 mL bottles (PET, PETG, and glass) and 30 mL glass bottles (from our line, that is Lugol's 66, only, however this item includes a dropper cap, so there is no need to purchase an additional one). 
For 30 mL PET and PETG bottles (all Captiv8 formulations packaged in 30 mL volume excluding Lugol's 66), use our 1.5 mL US-made pipette.
