I created a new PyroComponent YouTube channel. I do not know yet what I will publish on the old channel. All new reviews and more will be on my new channel.

New video about Paper Hemi-shell 1,5-16" on my new YouTube channel. You can see a detailed overview as well as the principle of manufacturing display shells.

Subscribe to my channel and follow the news.
