i don't know is everyone can directly buy from him,
i would like to help if more than 10 people want to buy & got problem.
the price for silicone is us$2.25 + $2(local shipping cost)+shipping cost to yr country(most country is us$2 by airmail, +2for register mail)+3%paypal handling(not for me, only because paypal will charge me handling, i didn't earn any)
that means total is bout us$9 for 1, but send 2 should just add us$2.25, that means buy 2 colour just about us$11.25
let's see how many people need it.
