Thin uPVC trim

I've recently fitted a new window in my bathroom, and there's a small gap on the inside between the edge of the window frame and the tiles.
I'm looking for some thin (say 1-2mm) white uPVC trim approx 30mm wide and around 2m in length to bond to the frame/tiles to cover this gap, similar to this.

Does anyone know where I can get such thing from that doesn't have a minimum order? (the place linked to above has a minimum order of 12 strips costing some £60 )

Thanks

Are you near any Mr Plastic, they are in 5m length but still cheaper, I know Wickes do them, just my opinion, I think the quadrant looks better than flat strip on the window then finish off with Delux decorater white caulk

Could not put in strip of tiles instead?

As masona says, Wickes do various uPVC cloaking profiles and from memory (as I don't buy from Wickes very often since they're a bit pricey for some items), they come in either 35mm, 65mm, or 95mm widths at 2.4m length and pproximately 5mm thick (I think).

They also have various quadrant profiles available so it's up to you which you prefer.

Thanks guys... Did have a look in Wickes but as usual in our local one, most stuff is out of stock, I'll try them again or a different branch.

Not near a MrPlastic, I'm across the other side of London.

I did think about tiling it, probably will in the future, but I didn't fit the current tiles so have no idea where they came from, and in reality it'd only need one or two tiles to do the job, not a whole box (they're big tiles).
