lidded cups / beakers for toddler groups

[Bookswapper]

I have been allocated the task of replacing 30 beakers for my toddler group. They need lids but no valves or anything complicated.
I thought it would be easy but its harder than you think just getting simple, cheap beakers.
Can anyone direct me to a source, online or otherwise?

What about this one

Might be able to get it else where sometimes made by tommie tippee.

Asda do packs for about £2 with lids with spouts which are easy to wash

our use the tommee tippee first cups like the mothercare one linked above! older ones use them without the lids!

Ikea

Poundland have got the tommee tippee brand ones in at the moment - costing £1 funnily enough!
