View-Master custom reels started in the era of the blue ring reel. Commercial and private issues have been produced for a multitude of reasons, commercial advertising being the most prevalent. Weddings, medical applications, and other special events also account for a fair number of these reels.

Early reels were able to be ordered in small numbers of 25 or more, thus making them very hard to find. Modern custom reel production at Fisher Price has a minimum run of 100 reels available.

A fantastic alternative now also exists:

Former View-Master staff photographer Rich Dubnow has been producing custom reels since the closing of the Portland, Oregon plant. His company Image3D does runs of all sizes starting with as little as ten reels.

The reels are not the usual View-Master format, but are more like a huge slide.
The reels will work in all standard viewers. Other 3D formats are also available.
