Playtex beakers with straw - any idea where to get them in the UK?

[extremelychocolateymilkroll]

I met someone who recommended these beakers which come from the US but she thought were on sale in the UK. They are the only beaker she has tried which don't spill. Have had a look on the internet and can't seem to see the one she had. It was a tall beaker with a ridged cover you could push back and forth. Is anyone familiar with these beakers? TIA

we got ours from costco about a yr ago so dont know if they still do them

Thanks bubblagirl.
