Hi , sir . Come and have a look here . We have all kinds of sweaters .  I ’ m looking for a sweater for my wife . Tomorrow is her birthday . And I know she needs a woolen sweater .  How do you like this grey one ? It ’ s pure wool , one hundred percent of Xinjiang wool .  It feels good . Are there cowl-neck pullovers with the same color ? My wife prefers a turtleneck to a V-shaped collar .  Yes , we do . What size do you want ?  Size one . By the way , what if I bring home this sweater and my wife doesn ’ t like it ?  Well , you can always bring it back to us for a full refund .  All right . Could I have it gift-wrapped , please ?  Yes , just a moment , please . 
Yes
