Which of these wedding presents is better?

My friend is getting married in 2 weeks...she did not make a gift registry....she just wanted people to get what they wanted. I don't have much of a budget...I don't want to get her something for her house as he taste is SO specific and I know I will get it wrong...I thought of either making up a honeymoon basket with his n hers dressing gowns, a book of poetry, cups and saucers and hot chocolate and chocolates and something else....or getting him a hip flask or cuff links engraved with initials and the wedding date....and her a silver pendant...I know her jewelry style well....so which gift is better in your opinion? Gift basket or hip flask/cuff links and pendant?
