The pingal is plastic.

The brush, on the other hand, is assembled since the handle (two pieces), the brush itself, and the cap are screwed together... I believe that the brush will unscrew at some point during use, which is definitely not an experience I want to go through...

For the 21.5 euros I paid to acquire the product, the first impressions are very negative in terms of its quality, as it is not at all value for money! I would not buy it again.
