yes still in stock
10 ksc75 available now.
price including postage to peninsular is RM84, add RM6 to get a pair of ksc75 compatible cushions!

it's original but no receipt will be provided.

the reasons no receipt is provided are simple:
1. you do not need receipt to claim for its lifetime warranty, in case you need to, because it's lifetime.
2. the earphone does not have individual serial number, so you cannot prove that the receipt is for that specific earphone.

so, if you are end user, receipt is not important unless you want to use it to claim for tax exemption.

hope it helps.
