The basic design of Stanley mug, whether they are plastic or stainless steel is the same – a double wall insulation with a lid to cover the top. But although the stainless steel version costs more than plastic versions, in the long run, they are the best deal for travelers. They can also be made of ceramic or glass, but they are generally designed for household use and not to travel because of the possibility of damages.
The main benefit of Stanley mug is durability and better insulation. Tough steel, and despite the plastic mugs can take a beating, stainless mug can last much longer. This is especially true when compared with the more brittle, hard plastic mugs that are sometimes used to display stylish designs and finishes. Although messy, dropping a steel cup of coffee will not generally cause damage.
There are three basic types of insulation used; air, foam or vacuum between the double walls. Plastic versions typically use air or foam. Both works received, but air or foam is not effective as a vacuum insulation. More often than not, use a steel mug vacuum insulation to keep drinks hot for long periods of time. This can be especially important on a long congestion morning. Fortunately, there are many different types of Stanley mug are available on the Internet.
