DEEN.J thin spanner 14x17mm

This thin spanner is sent to the store
"Is there a spanner that can be used well even if it's thin?"
This is the one that started the project to meet the opinion.
Although it is an item under development, it is a product that is definitely manufactured in a famous factory that supplies OEM to major French and American tool manufacturers.
I would like to create a new product that aggregates your opinions such as "If it was a little more".
