We spotted a special promo on the In-flight Duty Free Store magazine of HK Airlines recently – purchase Camus Cognac & get a classy wallet as a gift with purchase.
Notice: Camus Cognac has a subtle approach to branding on its promotional product giveaways – preferring not to have overly intrusive logos so as not to affect the overall vibe and perceived value of the wallet.
Rather the brand focuses on rewarding its customers, giving them the best for their money. 
ODM advise: Whenever promotional apparel/bags/wallets are concerned, keep your branding subtle like Camus to ensure repeat usage. You definitely do not want to make your customer feel like he’s a walking billboard or advertisement.
