Hello PoshPoints Members, up for your consideration is a brand new set of four, camping mugs. They are Stainless Steel with plastic handles (not sure how the handles are attached, since there is no holes directly through the mug). These are stackable inside the included holder. The holder is made os Stainless Steel and the base is plastic, making it easy to drill holes through it in order to be mounted to your RV countertop or a picnic table. The mugs are approximately 3" tall and have a diameter of about 2". I have shown a picture for comparason with one of the camping mugs next to a regular size coffee mug (not included). Each mug can hold appriximately 6oz of liquid.
