I'd potentially be interested in purchasing one of these, but I think £6 shipping from the US is a bit strong for just one item. As mentioned above, if we bought in bulk, would the shipping remain the same? I cant imagine they weigh very much, so here's hoping!
What's the actual product price?
Your colours look great, but dont forget you're also competing with UK products such as this -
