If it is about several centimeters in width it will manage somehow. Since length (length) has a stopper it is OK if you buy something slightly longer. As expected it is good to build with Tachikawa brand.
I was looking for something that fits well without ordering. It was regrettable that the length was 10 cm shorter. Since the next size will be 30 cm longer, it is a perfect score if there is a slight difference in size.
