MonotaRO's rubber part of the old product deteriorated in a short time and received a great scold from the agent (department store). The amount of damage for the exchange was also enormous. This time it is not rubber but to say nylon, so I decided to use it terribly.
We are very satisfied that what we actually used as waste disposal can be used in Kannan work. I would like to continue using it in the future. It is easy to understand if there is an engraving of L in the locking direction and F of the releasing side.
