They're trying to save the environment, one cup of coffee at a time.
Five students at St Mary's Diocesan School for Girls have launched a reusable cup business under the young Enterprise Scheme.
CEO of Cup & Go, Mirei Kondo (19) says the group wanted to come up with a business which would have a positive impact on the environment.
"Every day people buy hot drinks on their way to work or school which is served in a single use cup that ends up in the landfill. We wanted to change that."
Mirei says they are targeting a broad range of people with their product, a resusable travel cup for hot drinks.
"People aged from 12 to over 65 buy hot drinks as a takeaway item, so we are hoping to encourage people to choose to purchase our cups and use those instead."
Gracie Thomas, who is the financial director for the group, was also responsible for the design of the cups.
She says they chose bright colours as their market research told them those colours appealed to the most people.
"Eventually we will also have them in red and white, however our supplier couldn't get those colours for us at the start, so they will be introduced to the range later on."
