Please note that prototypes are sold as-is. They are not eligible for return or replacement because they are sold final sale and as-is. Full disclosure, this is my very first prototype of the Pocket Loom product line, so there's a lot that's different that I figured out in later prototypes. Differences from finished product The loom doesn't have the diagonal or horizontal cross-braces to prevent the sides from flexing out slightly under high warp tension I hadn't quite gotten my math right (whoopsie) for the dent spacing yet Does not include the small tag on the bag drawstring labeling it with size and dent Does not include a heddle roller Does not include a needle or shuttle The comb handle is itty bitty The sides of the loom don't have the V-notches for capturing warp thread The loom doesn't have the bumps to hold the heddle roller in place Cosmetic flaws The heddle roller has some minor wear on it from weaving a sample There are some minor gaps in the top layer of printing from setting the printer to a lower detail, faster spec The corners of the underside of the loom are a little scraggly, as well as some parts of the underside of the comb The loom is labeled "0.1" in Sharpie on the underside so I can tell it apart from my later prototypes more easily Click here to view the regular product details.
