Hi there, I have a Furyu 8 shinobue, which case will fit it?

The maker says that baby 7 has about 390mm×19mm (with pudding) ／ about 410mm×19mm (without pudding) and it would fit with furyu-8, which has 19mm in width and 410mm in length. Shinobue is made of bamboo and there might be a different length one (it doesn't fit with ). Please measure your shinobue in advance and pick up a bigger case.
