40oz Rainbow Big Jack Stainless Steel Tumbler – Sublimation & UV DTF Blank

Bold, beautiful, and built for all-day hydration — our 40oz rainbow Big Jack stainless steel tumbler is a premium, large-capacity personalised drinkware blank compatible with both sublimation and UV DTF printing. At a generous 40oz capacity, the Big Jack is the ultimate companion for long days, outdoor adventures, gym sessions, and anyone who takes their hydration seriously. Sublimation requires a 3D press or convection oven at 200°C for 5 minutes per side using shrink wrap — producing vibrant, permanent, wrap-around designs that bond directly into the stainless steel coating. UV DTF wraps offer an equally stunning alternative for detailed, full-colour artwork with no heat press required.
