Baserat på kundernas feedback under 2020 och 2021, uppgraderade Carkin en av sina befintliga tumlare och lanserade det nya föremålet i oktober 20 oz raka DUO skinny!

The Speede Custom's gave us an very good example about--why we use stainless tumblers instead of disposable cups? By using different decoration methods, the stainless cups/bottles/mugs could be very impressive and memorable!
