Imagine that it's your father's birthday. Look at the photographs and think which of these things you would buy him.
Great! That's what they are.
There is no need to use 'the' in this list, though. You can simply write, "wallet, boots and briefcase".
Or, you could write, "a wallet, some boots and a briefcase." Either is fine.
Good. No problem describing the items as you have done.
