Spot tampering with a glance—a security ring separates from the lid of these bottles the first time you twist it off. Made of aluminum, these bottles resist corrosion from cleaners, solvents, and mild acids—they’re also lightweight. They are tested to meet United Nations regulations for packaging and shipping hazardous material over land, sea, or air. The regulations aim to prevent hazardous spills caused by accidents or rough handling.

Note: It is the responsibility of the shipper to follow regulatory guidelines for properly packaging and labeling all hazardous materials and ensure the appropriate method for shipping.
