Ukara / VCRA is UK only. Hobbyking is china, so they probably don't know about it / don't care. Usually their shops state that it's your responsibility to deal with the customs of your country.
Hope that the customs will want to ask you about your defence instead of just destroying your stuff.
I'm thinking of buying some stuff from them (including a gbb pistol) but how did you know it came from UK wear house and did it have the same low prices??
