For those who are looking for something special to cover their suitcase, you can consider getting some SUSHI theme cover which I see it is simply interesting. I found about this when I glazing through the web where the Japanese retailer Parco expended their selection to new types of sushi case which includes tako (octopus), ikura (salmon roe), and saba (mackerel). Each suitcase cover slips over a suitcase and leaves openings for the handle and wheels.
The sushi case seems pretty interesting like what you have at the Japanese Restaurant conveyour belt.
Each of it is at Y3024. Unfortunately they did not served overseas
