Cassette case for S2

Hi I'm planning to buy Cassette type Silicon Case for Samsung S2 for a long time and now I found a link which matches my favorite color.

White Retro Cassette Tape Silicone Case Cover For SamSung Galaxy S2 i9100 -SO8 | eBay

If I buy from seller's city [Hong Kong], do I have to pay extra money other than the case amount.

Please reply soon thx
