When he already owns everything practical the gift needs to be an experience or something genuinely premium that he would not buy for himself. High-end whisky, a bespoke item, a rare collectible or a luxury service appeals to someone who has already covered the basics. The key is choosing something that has genuine value beyond the price tag. A masterclass from an expert in something he loves, a subscription to a premium service, or an exclusive item from a niche maker works far better than just buying an expensive version of something ordinary. These gifts should feel special because they are rare or unique rather than just expensive. He will appreciate the thought that went into finding something he could not easily get elsewhere.
