Don't worry about it Olly.
I'm sure you can see how you might have come accross though. If you want to give it a shot making them at school, please be my guest dude, but make another thread.
This guy has been making them for over 2 seasons now for his own team and seems to have the right materials and production method down pat to create a lovely finish.
I have a single set on the way so I can test them and let y'all know if they're all they're hyped up to be.
And remember - £15 is the MAXIMUM price they will be INCLUDING shipping to your door and paypal. I'd say that's pretty reasonable and it'll be cheaper if we get a good number ordered.
