NIIMBOT Labels for B1/B21/B31 Label Maker, 50 x 30 mm (1.97'' x 1.18'') 230 Tapes/Roll
Quick take
These NIIMBOT direct thermal labels are a replacement roll made for the NIIMBOT B1, B21, and B31 portable Bluetooth label makers. They’re built for clear, easy-to-read prints and durable everyday sticking, and they work with the NIIMBOT app for labeling templates and repeat jobs. The biggest thing to get right is compatibility and setup, including matching the label size in the app and dialing in print density if your output looks light.
Pros and cons
Pros
- Direct thermal printing, no ink or toner required (designed to produce sharp text and scannable codes).
- Waterproof and oil-proof label material, plus tearproof claims for everyday durability.
- Strong, residue-free removal is part of the design intent (buyer sentiment supports good adhesion for home and office use).
- App templates and customizable saving are described as making repeat labeling faster.
Cons
- Best fit is specifically for NIIMBOT B1/B21/B31 models, so cross-model compatibility is not the goal here.
- Print clarity can require app and printer adjustments, like setting the correct label size and adjusting print density.
- Limited buyer-review evidence specific to long-term, harsh-environment performance beyond general durability impressions.
What buyers think
Buyer-review evidence points to consistently readable output, with multiple comments emphasizing crisp text and codes (barcodes and QR codes) that are easy to scan. Reviews also describe smooth day-to-day use, including quick setup in the NIIMBOT app and the convenience of templates for faster labeling. On durability, buyers generally feel the labels adhere well for common home, office, and small business tasks. Evidence is also limited but suggests that occasional alignment or print positioning issues can happen, with users resolving it by restarting the printer, and by confirming the label size and print density settings when needed.
What these labels are designed to do
These replacement labels are built for direct thermal printing with NIIMBOT’s B1, B21, and B31 portable label makers. The 50 x 30 mm (1.97 x 1.18 inch) size is intended for the label templates and layout options in the NIIMBOT app workflow, so your text, barcodes, and QR codes land correctly.
Key specs that matter for everyday use
- Label size: 50 x 30 mm (1.97 x 1.18 inch), white labels on a roll.
- How it prints: Direct thermal (no ink or toner).
- Quantity: 230 labels per roll.
- Material and finish: Plastic material, uncoated finish type (as listed), rectangular shape.
- Durability claims: Waterproof, oil-proof, and tearproof, plus “leaves no trace” and “no residue left” removal intent.
- Adhesive behavior: Designed for stronger adhesiveness with easy removal per the product notes.
- Clear output for codes and text: Buyer feedback consistently mentions readability.
- Designed to handle real-world mess: Waterproof and oil-proof claims plus tearproof positioning.
- Workflow that supports speed: App templates and saving repeat setups are called out.
- Easy replacement: Roll format designed for ongoing labeling needs.
- Compatibility is model-specific: You’ll want to ensure you own the NIIMBOT B1/B21/B31 label maker.
- Setup affects results: Clear printing may require adjusting print density and confirming label size settings.
- Alignment quirks can appear: Some buyers mention occasional alignment issues, typically resolved quickly by restarting and checking settings, but detailed evidence is limited.
- Owners of NIIMBOT B1, B21, or B31 portable label makers who need a replacement roll in 50 x 30 mm.
- Home organizers and office users who want labels that are readable at a glance, including QR codes and barcodes.
- Small business setups that do repeat labeling and want an app template workflow.
- People labeling items where basic water and oil resistance is useful (kitchen storage, workshop items, and similar use cases).
- You need labels for a different label maker model or a different label size, because this roll is designed around the B1/B21/B31 and the listed dimensions.
- You prefer a “plug-and-print” experience with no app tuning, since print density and label size settings can matter for best clarity.
Print quality and scanning: what to expect
Review themes emphasize that prints come out clear and sharp, including text and scannable codes. That said, there are setup variables that can affect output. If prints look too light, the printer density setting is relevant (the product notes mention adjusting print density in the print interface). Also, if label content looks offset, it helps to confirm that the label size selected in the app matches the physical label roll size.
Adhesion and durability for home and office labeling
These are positioned as “tough everyday” labels, with waterproof and oil-proof claims and tearproof durability. Buyers commonly describe the labels as sticking well and holding up across typical organization uses like filing, storage labeling, and small business tagging. If you label items that see moisture or oily handling, the intended material properties are the reason this roll is a good match.

Price and availability
These labels are typically sold as single replacement rolls. Availability can change, so it’s worth checking the current listing price before you reorder, especially if you label frequently or in bulk.
Alternatives to consider
If you are comparing options, the main decision factors are label size compatibility, whether the printer is direct thermal, and the adhesive and durability needs for your surfaces. If you need a different size than 50 x 30 mm, or your device is not one of the NIIMBOT B1/B21/B31 models, you’ll want to look for labels explicitly made for your specific label maker and template size in the NIIMBOT app. If you label items that require very specific material performance, prioritize products that clearly state the durability and adhesive behavior relevant to your environment.
