The main body is made from SLS 3D-printed nylon (laser printing), not an FDM printer with PLA filament, so it will last. Close and open with magnets, a magnifying glass is also folded within the packaging. The one in the picture has been travelling with me for over a year, fully tested and still smooth. 

Please get in touch with me first before you placing the order, I may not have stock and the leadtime will be around 2-3 weeks.

I have other interesting stuff designed for your Bronica, like an Instax back. Do check out my shop.  

More details for this part is in the video below. 

* Design updated, better quality overall.
