How do I get missing parts for a Cobi set?

Question

I got the 1305 set from Cobi. I am missing 3 or more pieces. I can't complete the model without these pieces:

• 2 normal black 1 cm high, 6 studs long, rectangular (not round edge)
• 1 black rectangular flat 3 studs long, 2 studs wide.

How do I order only these parts?

Answer 1

You can order individual parts using Blocks by Piece.

I think the two parts you describe are 2x6 czarny and 2x3 1/3.
