Each personalization design will be a stainless steel silver colour. We use a laser engraver to make each design on the winesulator. The engraving is permanent, it will not come off when washing and will last. Each winsulator holds a full bottle of wine, has leak proof cap, maintains the perfect temperature for 24+ hours and is glass-free zone friendly. Any custom order with profane/lewd content or copyright infringement is subject to cancellation.
