This package contains two 24-oz stainless steel water bottles with insulated walls. The bottles have FreeSip spouts and push-button lids, which can keep beverages cold for a whole day. The patented FreeSip spouts are designed for sipping through built-in straws or swigging from wide-mouth spout openings. The lids, which can be easily opened by pushing, come with locking carry loops to ensure cleanliness of the spouts. The wide-mouth openings allow for easy cleaning and adding ice, while the bases are compatible with most cup holders. The bottles are free from BPA, lead, and phthalates. The cups should be washed by hand, while the lids can be safely cleaned in a dishwasher.
