For example if my name is Samantha Marie Jones my monogram would be SMJ. For an additional fee we can add something special to the back of the tumbler, just visit the add on options. Name size will vary depending on length of name. Double insulated stainless steel tumbler Keeps drinks hot up to 6hrs and cold up to 20hrs.
