Wow! These reading glasses are not only made from recycled Ocean Bound Plastic from Plastic Bank®, but they are also available in different strengths. They are a perfect, sustainable, and socially responsible giveaway. With the purchase of this product, you support Plastic Bank®, an international organization with two main goals: reducing poverty and reducing plastic waste in the oceans. Plastic Bank® pays people in developing countries to return plastic waste, which is collected from beaches, rivers, riverbanks, landfills, and the shallow parts of the ocean. This helps prevent plastic waste from polluting the oceans. The collected plastic is sorted, cleaned, and processed into granules, which are then used to make new products labeled as Social Plastic®. Each item can be supplied in an individual brown cardboard box for optional personalization.
