BAI Embroidery Bobbins Type L
Product description
For embroidery work that runs through multiple designs, a ready-wound bobbin can cut down on winding stops. These BAI bobbins come in a 144-piece pack for ongoing production or frequent projects.
The listed version uses white 70D/2 thread and Type L, plastic-sided bobbins. That makes the key buying check simple: match the bobbin type and thread to your machine and the work you plan to do.
Technical details
This pack contains 144 prewound bobbins with white thread, identified as 70D/2 and 60WT. The bobbins have plastic sides and a Type L / SA155 format. The product is presented for embroidery use, including hats, apparel, and logos, as well as commercial sewing work.
A bulk pack is useful when several bobbins may be needed during a production run. For example, an embroidery shop preparing a batch of logo caps can keep replacement bobbins ready rather than pausing to wind each one. The tradeoff is that a pack of 144 may be more than a casual user needs, and the listing does not specify how much thread is wound onto each bobbin.
Compatibility & requirements
The maker describes these as compatible with most multi-needle embroidery machines and commercial sewing machines. That is not a guarantee for every machine: Type L / SA155 is the defining format, so compare it with the bobbin type your equipment calls for before ordering. The listing does not name specific machine models.
It suits you if your machine takes Type L bobbins and you want prewound white thread for repeated embroidery work. You may want to skip it if your setup requires a different bobbin format, or if you need black or mixed-color thread, this specific listing is white.
Usage tips
Keep the bobbins stored clean and dry, and separate them from other bobbin types so the Type L format is easy to identify when changing thread. For a new design or unfamiliar fabric, try a bobbin during a small test run before committing to a full batch. This helps you spot any mismatch in fit or stitching behavior without assuming the bobbin will suit every setup.
The product description also mentions 75D/2 as a separate thread option, but this version is identified as 70D/2. Check the selected listing details if you are comparing thread options, do not assume this pack includes both. According to the maker, the plastic-sided design is intended to support smooth thread delivery and stable tension, though the listing provides no machine-specific performance results.
Questions before you buy
How many bobbins are included?
The listed pack contains 144 prewound bobbins.
What thread is on this version?
It is identified as white 70D/2 thread, also labeled 60WT in the product name.
Is it suitable for any sewing machine?
The maker says it works with most multi-needle embroidery machines and commercial sewing machines, but the listing does not confirm every model. Verify that your machine uses Type L / SA155 bobbins.
Final verdict
This BAI pack makes the most sense for embroidery users who already use Type L bobbins and want a ready-to-use supply of white thread for repeated hat, apparel, or logo work. Its 144-piece format favors regular use over occasional repairs, while the specific bobbin type limits it to machines that accept Type L / SA155. If your machine calls for another format or you need a different thread color, this is not the right version to choose.
