Find the model number and look for a LetraTag cassette
Read the model from the machine’s label or manual. Some retail titles use LT-100H, while DYMO’s product page says LetraTag 100H. Check the LetraTag name and 12 mm cassette family on the refill. A shop may display DYMO LabelManager supplies nearby, so match both the family and width before choosing the material.
| DYMO model | Cassette format | Useful refill options |
|---|---|---|
| LetraTag LT-100H | 12 mm LetraTag (LT) | White paper and plastic for everyday labels |
| LetraTag LT-100T | 12 mm LetraTag (LT) | Paper, plastic, metallic and iron-on in the manual |
| LetraTag 200B | 12 mm LetraTag (LT) | Paper, clear or opaque plastic, and textile |
| LabelManager 160 or 280 | Model-listed DYMO D1 | See the D1 guide for supported widths |
| LabelWriter 550 series | Authentic LabelWriter rolls | Match the exact printer and label roll |
A 100H owner can use the same featured paper or plastic refill in a 200B after upgrading to app printing. If the box says only “12 mm DYMO”, find the family on the packaging before buying. The same width occurs in several different machines.
Choose paper for files and dry indoor storage
DYMO’s S0721510, also sold as 91200, is black print on white paper. It contains one 12 mm × 4 m cassette. DYMO describes the paper format for indoor labelling. It suits a file tab, ring binder or indoor storage box that you expect to handle occasionally.
Paper is a useful default when you are making a set of labels for a dry project. Start with the labels you need now and keep spare length for updates. When a folder is reused, remove or replace the previous name before adding a fresh label so the remaining text is easy to read.

DYMO LetraTag white paper tape
One genuine white paper cassette for black text on files, folders and dry indoor storage.
Keep in mind. Use a 12 mm LetraTag label maker. Choose a different supported material for garments or surfaces that need regular wiping.

Use plastic for frequently handled labels
DYMO describes its white LetraTag plastic tape as tear-resistant. The featured pack contains one 12 mm × 4 m cassette and prints black on white. It suits indoor items that people pick up and put away regularly, such as a smooth drawer front or a reusable storage box.
Try one label on a clean, dry part of the item. Press the edges down and check the label after ordinary use. The result can depend on the surface, the adhesive and how often you handle or clean the item. If a label will be exposed to repeated washing, heat or outdoor weather, use the manufacturer’s instructions for the exact material and conditions.

DYMO LetraTag white plastic tape
A genuine LetraTag plastic cassette that prints black on white. It suits frequently handled indoor labels such as drawer fronts and storage boxes.
Keep in mind. Use a LetraTag label maker, such as the 100H or 200B. Check the adhesive on an inconspicuous area if the surface is textured or delicate.

Choose clear, metallic or textile tape for a specific job
Clear plastic lets the object’s own colour show around the lettering. Check the contrast before making a batch. On a dark box or a jar filled with dark contents, black text on a clear backing may be harder to read than black on white. On light, smooth containers, it can be a good way to keep the label visually discreet.
Use a listed metallic LetraTag option when you want that finish and your exact model supports it. The 100T quick guide lists metallic among its cassette materials. For a label that needs to be seen easily in a dim cupboard, try a sample in the light where it will be read.
For a garment or fabric bag, look for the specific LetraTag iron-on textile cassette, and check both the tape instructions and the garment’s care label. The application method matters as much as the cassette fit. Set aside one piece to check how the tape and fabric behave together before labelling a batch of clothes.
Fit the new cassette and preview the first label
Open the cassette compartment and check the loading diagram for your model. Seat the cassette so the tape passes between the print head and roller as shown, and close the cover. The 100T quick guide shows the cassette clicking into position. Use the exact model’s instructions if your compartment or controls look different.
On the 100H or 100T, enter a short name and preview it using the handheld controls. On the 200B, choose the printer and design in LetraTag Connect. Print a short sample before using the whole list of names. If a long label is hard to read, try a short main name or place a secondary detail on a second line.
Record the cassette code, material and pack count
Keep the empty box or take a note of the exact code. Paper and white plastic can have the same width, length and colour, so a photograph of the finished label may leave the material unclear. A marketplace listing may group colours and multipacks. Check the selected material, cassette quantity and length per cassette.
Compare two packs using the delivered cost and total tape length when the material and width match. Count starter cassettes separately if you are also comparing machine bundles. For infrequent filing, one known compatible refill can be enough. For routine box labels, keeping the same tape helps maintain the same appearance and makes repeat orders simpler.

Common questions
Do the LetraTag 100H and 200B use the same tape?
Yes. Both support 12 mm LetraTag paper and plastic cassettes. The 100H prints from its own controls and the 200B uses the LetraTag Connect app. That difference does not change the family of tape you buy.
Can I use 12 mm DYMO D1 tape in a LetraTag?
Buy a 12 mm cassette marked LetraTag or LT for a LetraTag machine. D1 belongs to a separate DYMO system used by compatible LabelManager models and the cassette side of supported LabelWriter Duo printers.
Is 91200 the same paper refill as S0721510?
UK listings use both references for the genuine black-on-white LetraTag paper cassette. The manufacturer lists S0721510 as 12 mm wide and 4 m long. Check the material and pack count as well as the number.
Which LetraTag tape should I buy for clothes?
Choose the genuine LetraTag iron-on textile tape listed for your model. Read the tape’s application instructions and the garment’s care label before using an iron.
Does changing from paper to plastic give me a wider label?
Both featured cassettes are 12 mm wide. The difference is the material. If the text is crowded, preview a shorter label or use a suitable two-line layout within your model’s formatting options.
