300 micron laminating pouches?

I am trying to get hold of 300 micron laminating pouches but all I can seem to find is 250 and 350…. Can anyone tell me where I might find and buy them in the UK (online or in store), and preferably in London. Thanks for your help!

try local stationers! i have had some from hobbycraft befor, so try their website to see if there is one near you! i think i have seen them in both partners and whsmiths to! good luck!
