6-pack of 16 dram vials with child-resistant lids. Amber color helps to protect the items inside from damage caused by exposure to light. Meets all USP required testing. Each bottle includes a child resistant cap and a non child resistant snap on cap. Dimensions: 2 7/8 inches interior height & 1 1/4 inches interior diameter. Perfect for 15ml size eliquid bottles. Please note: there is no such thing as "child-proof". Do not depend solely on the child-resistant cap for keeping your kids safe.
