Idk about a championship belt, lol. If you ask me personally, I might just go with a cake and flowers. But as we are discussing ideas, I recently went to this shop in Dubai while browsing a gift for a friend. I saw a rechargeable diffuser, and it is something that can be used regardless of the occasion. May it is a corporate event, just the office, or a gesture of appreciation, it is the best item to give to someone. You will find it sitting there, reminding them of your goodwill.
