I am often asked. What product should they buy to fit a certain audience. Hands down it's Tumblers for adult venues.
With such a great variety to choose from. You may want to start your buying process with do you want Form or Function.
Because so many items end up in people's junk drawer is the reason you don't want to give what they call "trash and trinkets".
A tumbler can start a great conversation between you and your customer, when you are using it as your door opener.
