I run a small company that sells physical products, so labels are not decoration for me — they go on shipments, jars and price tags every week. I was writing names and prices on stickers by hand and it looked like it. I bought the NELKO Genuine P21 label tape in Blue, Yellow and Pink to fix that, and the colors are the part customers mention first.

Quick verdict
If you already own a Nelko P21 label maker, this three-roll pack is the cheapest way to make your labels look deliberate instead of homemade. You get 540 labels across three colors, printed in black on colored tape, with no ink or toner to rebuy. The chip on each strip tells the printer what size roll is loaded, so you drop it in, close the lid and print. For a business where the customer sees the label before they see the product, the color is doing real work — I color-code product lines now instead of writing the category out. check current price on Amazon
Why I bought it
I sell stuff, and until I bought this every order went out with a handwritten sticker on it. That works when you ship three things a month. It stops working when you ship regularly and the labels are the only branding the customer sees on the outside of the box. I wanted labels that looked like a company made them, not like someone with a marker and no time.
I could have bought plain white tape and been done. I went with the Blue/Yellow/Pink pack because color does something text can’t: it sorts things at a glance. Customers can tell two product lines apart without reading the label at all, and I can find what I’m looking for on a shelf without squinting.
The other reason was the printer side of it. A P21 only prints black text, so the color has to come from the tape itself. Buying the colors as rolls instead of trying to print them is the only way it works, and this pack is the cheap way to do it.
What the NELKO P21 label maker tape is like to use
The honest answer is that it’s uneventful, and that’s the point. Load a roll, the printer recognizes the size of the tape, print, peel. I swap between the three colors depending on what I’m labeling, and the whole switch takes seconds. There’s no ink cartridge, no drying time and nothing to smudge when I pick the label up straight off the strip.
What sold me — and what customers keep reacting to — is how much better a plain black label looks on colored tape than on white. I use blue and yellow for the two things I sell most, and pink for anything that’s a sample or a gift. That’s a system I built in about ten minutes, and it’s the first labeling thing I’ve done that clients have actually commented on.
Printing only what I need matters too. These come as rolls, so I print five labels or fifty and nothing is wasted in between. The listing says the tape is waterproof, oil-resistant, tear-resistant and scratch-resistant with no BPA, and I can say the labels hold on the surfaces I use them on — paper, plastic packaging and glass jars — without lifting at the corners.
One thing to know before you start: each strip has a small green chip sticker on it. That chip is what tells the printer the roll size and keeps the alignment right, so don’t peel it off or tear it. I nearly did on the first roll because it looks like packaging.

Who should skip it
Skip it if you don’t own a Nelko P21 — the tape is built around that printer and the chip in the strip, so it won’t run in another machine. Skip it if you want longer labels than 14x40mm or continuous tape, because the length is fixed per label. And if your labeling is purely internal and nobody outside your business ever reads it, plain white tape will do the same job for less.
FAQ
Does NELKO P21 label maker tape work with other label makers?
No. This tape is made for the NELKO P21 portable label maker and uses a chip on the strip that the printer reads to recognize the roll size. Other brands’ handheld printers use their own cassettes, so don’t expect it to fit a different machine. The listing also warns that tearing the chip or the green sticker off will affect print quality and alignment.
Can you print in color with the P21 and this tape?
The P21 prints black text only, so the color comes from the tape itself and not from ink. That’s exactly why this pack exists — you get Blue, Yellow and Pink rolls and choose the one you want before printing. It also means you’ll never buy ink or toner for it, since thermal printing uses heat instead.
How many labels come on the three-roll pack?
Each roll carries 180 labels at 14x40mm, so the pack gives you 540 labels in total, split across the three colors. Because it comes in rolls rather than pre-cut sheets, you print only the number you need at any one time and nothing goes to waste.
Bottom line
I bought this to make labels I wasn’t embarrassed to put on my own products, and the colors turned out to be the useful part — customers read them, and a shelf of my stock sorts itself. It’s not a flashy purchase and it isn’t meant to be. It’s tape that makes an already-cheap label printer produce labels that look like a business made them. check current price on Amazon
