For On-Demand, fully customizable bridgework merchandise, visit my store on zazzle.com.
I have personally ordered multiple products from zazzle over the years, and can vouch for the overall quality of their products, and their customer service is excellent if/when something doesn't meet expectations.
Zazzle makes it convenient for a guy like myself to offer a variety of quality products, without having to produce a big inventory of items and sell/ship them myself. You can also customize items using the graphics I have stored on the site, and create exactly what it is you want for yourself.
Keep scrolling down for pictures of actual products I ordered through Zazzle (sorry I didn't iron them before I took photos). Always keep an eye out for promo codes because they often have amazing sales.
