To wonder what I can buy for a 50th?

[RainbowBriteUk]

My friend (male) is turning 50 soon. I want to get a gift for him that shows I care but money is tight. I have around £20 max to spend.

He likes food and nice stationery.

Thanks :)

How about some food, or some nice stationery?

Seriously, how about some assorted olive oils, infused with herbs and stuff?

Anthropologie notebook?

Got an old photo of you together? You could frame it for him.

I bought this for myself a while back, and it's In the sale now. It's really beautiful and the map cover would appeal to men as well I think. Mine is A5, but there's different sizes and you can buy refills for it.

I got a friend a pair of cuff links.

My llink failed, it's a Filofax Clipbook Retro Map cover

Has he got a garden? a fruit tree or two might be nice.

A nice tree is a great idea if he has a garden. If he doesn't but has space indoors you could buy him a lemon bush.
