Stone & Sling review for NinjaPOD: DTF Print on Demand

Dec. 18, 2025

We’ve been using Ninja’s consumable products for quite some time, including DTF supplies that we also print in-house, and their products have consistently been phenomenal — from DTF transfers to patches. Because of that positive experience, we decided to transition part of our operation to Ninja’s Print-on-Demand service to reduce internal workload and expand our product offerings without the burden of warehousing large amounts of inventory. We recently rebranded and are currently soft-launching our new brand using Ninja POD. Overall, the print quality has been solid. Occasionally, we’ve seen minor issues such as crooked or slightly misaligned design placements. To Ninja’s credit, every issue that didn’t pass our strict quality control was reprinted promptly and without pushback. That said, communication is where things could improve. While corrected products do arrive a few days later, there is often little to no correspondence when an issue is reported. As a POD provider, Ninja isn’t just a vendor — they’re a business partner — and even a short acknowledgment or update would go a long way. The app functions reasonably well, especially considering Ninja is newer to the POD space, and improvements do seem to be ongoing. However, there are some areas that need attention. Mockups, in particular, are a challenge. On several hoodies, the design editor places artwork too high, overlapping the hood, which forces you to compress the artwork height and distort the aspect ratio — even though 11” x 16” prints are stated as supported. Some products are missing proper placement boxes altogether, including pocket placements, or have placement boxes positioned outside the actual garment. Sleeve mockups look especially rough and resemble animated mannequin renders rather than realistic apparel. More lifestyle mockup choices would also be nice. Especially for back prints. The ability to remove/hide the default branding tags and/or replace with custom tags in the mockups would be great. Additional app issues include the inability to fully delete products from the system — deleted product names remain reserved, which makes reusing names difficult later. A bulk edit or bulk delete feature is also badly needed. Deleting products one by one, especially when the app returns you to the first page each time, is inefficient and frustrating. Looking forward, there are several features that would significantly elevate the platform. It would be great to see more transfer options available in POD, such as glitter, puff, foil, and glow-in-the-dark. Patch hats or embroidered hat options would also be a welcome addition, as DTF is not ideal for headwear. Expanding beyond apparel into items like drinkware, candles, or other lifestyle products would help brands offer more variety. One of the most exciting potential improvements would be enhanced branding options — custom packaging, thank-you cards, or even small inserts like stickers or keychains. Since Ninja already does UV DTF extremely well, this feels like a natural next step to help brands create a more personalized unboxing experience rather than just a folded shirt in a poly bag. Customer service does appear to be improving, and the introduction of a chat feature is a positive step, though email response times could still be faster. They are also developing an inventory feature, which currently feels a bit rough around the edges, but given that this is peak season, some growing pains are understandable. Overall, when compared to other POD companies, choosing Ninja still feels like a smart decision. They are clearly on the right path, and we appreciate the effort they’re putting into improving the platform. We’re hopeful for a long, prosperous partnership as we grow together — and we fully expect to update this review to a 5-star rating once these improvements are realized.
