This 22-ounce plastic Water Bottle is an unbelievable value. The stainless steel base keeps the bottom from breaking when dropped, and the stainless steel lid screws on snugly with a silicone ring to keep from leaking. The PET material is BPA Free and very strong, will not crack or break if dropped. There is nothing to lose with this amazing water bottle for only CAD$2.00!! Do not use this bottle for hot liquids to prevent damage to the bottle body. Hand wash only.
