At this point in the City Gill project, we are no longer providing demos.  These rarely come back and are expensive to make.

No worries, we will send you a fully functional prototype made using laser sintered nylon 3D parts.

We are asking $80 to cover our materials cost, respirator assembly, shipping (~2-3 days), overhead (web site, LLC/ tax licenses, prototype development, testing, etc), and help grow our injection mold fund.

Send $80 via PayPal check transfer to . Add 3% if you use a credit card. Include your email and shipping address as well as preferred color(s) in the PayPal notes.

Ready to ship: Red, Green, White, Blue, Purple, Orange, and Yellow. Other colors take an additional two week.
