Ashiya Rosablan Folding Parasol Black/Gray

This is a parasol from Ashiya Rosablan.
It has been stored without being used much.
When I checked its operation, the latch when opening felt a little weak, but it's fine if you push it in firmly.
(I only own this one Rosablan parasol, so I can't compare to see if this is standard.)
Also, as shown in the 5th photo, there is a slight color difference along the folds. I don't think it's very noticeable, but please refrain from purchasing if you are concerned.
