Help to find storage baskets of a certain size please

[Hogu]

I'm trying to find 2 baskets to fit a shelf I have . They need to be 29-31cm wide x up to 23cm deep and up to 15cm high.
Everything I find it either a tad too big or way too small.

Any help please? I can't alter the shelf as it fits between two walls and I need the baskets for small storage.

Asda have some that fit, ''Wham studio storage boxes''. They're 17x25x11cm.

Thank you but I don't like the plastic type, I'm looking for rattan or wicker type as they are near my front door so want them to look good..

Ah, sorry.

The works do small baskets, 30x22x11cm. £4 each.

They are for hampers, but you could reuse the cellophane and bow, I'm sure.

Good size but they won't look quite right side by side as they taper out at the top. I need them to be more square if you see what I mean.

TK maxx Home Sense always have a good selection

Ikea Knagglig fit the dimensions but are wooden crate like so maybe don't look good enough?

Have a look at the website a place for everything

Maybe you could get some made exactly to fit from here:

Fantastic work made by a craftsman, I had a laundry basket made that I feel will probably end up with future grandchildren!
