I have ordered many pieces from this company... Including hefty-price bulks of up to 250 board games & pieces... If you are looking for a good prototype place, this is the place to go. I would argue that their products, while a little more expensive, have better quality than TheGameCrafter. They also seem to have faster shipping dates than TheGameCrafter as well, which is great for folks like me who are impatient.
Also, their website is the easiest designer tool to use. No specific size modeling needed, you can just use PNG files (I designed everything on Canva)... And if for some reason you have a piece that they think will look a little off, they will hold the product and send you an email to double check if the design is okay before they produce it.
Great staff, great quality, great turnaround time... ONLY complaint is the price... Especially the shipping (but that is to be expected coming from China). But for a prototype or stand-alone game, totally worth it.
