This is a tumbler with a double plastic wall. Definitely not use ones and throw away products. The double insulation adds both weights, as well as quality, feel to the product. The insulation also allows beverages to maintain their temperature no matter if they are hot or cold. A simple product that will be a definite hit at parties and better still it is a product that will be kept as a substitute for a regular mug during normal workdays. Have your logo stylishly branded onto this product and get your branding enhanced by this cup. We recommend using this product as a show bag filler or as part of a corporate gift to your clients.
