Review: Good value and makes for easy and quick changes on projects - I’ve used both the black and white bobbin threads in this little set and both stitched out great. Currently using the black bobbin on the project in the photo on my Brother F480. When I received the bobbins some of them had become unwound inside the box set, however once I rewound them it did not cause any issues when embroidering. Very happy, good price and would purchase again. Review: Try them! You will never wind your own again! - I have a brother V3 and I have been winding my own bobbins with the 10 provided cases and buying the brother specific thread for my machine-timely and costly. Wow. I am so glad I have tried these! Immediately notice there is much more thread on than when winding my own on the machine - no breakage or problems at all even with the black! And last a lot longer! Great price, great product, will most definitely purchase again! ## Features - 25 black prewound bobbins: 90WT/60S/2 polyester bobbin thread for machine embroidery, sewing and creative projects. - Size A Class 15 SA156: designed for compatible machines; check your bobbin size before use for the best fit. - Prewound design saves time: ready-to-use bobbins help reduce winding work and keep projects moving smoothly. - Clear storage case included: keeps bobbins organised, visible and easy to carry between sewing and embroidery tasks. - Black bobbin thread: ideal for dark fabrics, logos, lettering, patches, garments, accessories and discreet finishes. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B088ZN7YF7 | | Best Sellers Rank | 129,652 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 21 in Embroidery Machine Thread | | Brand | Simthread | | Brand Name | Simthread | | Colour | 90wt Black | | Customer Reviews | 4.7 out of 5 stars 3,840 Reviews | | Item Length | 274 Metres | | Item Thickness | 0.45 Inches | | Item Weight | 2.82 Ounces | | Item length | 274 Metres | | Item weight | 2.82 Ounces | | Manufacturer | Simthread LLC | | Material | Polyester | | Material Composition | polyester | | Material Type | Polyester | | Product Care Instructions | Hand Wash Only | | Product care instructions | Hand Wash Only | | UPC | 822360839379 | | Unit Count | 3200.4 meter | ## Product Details - **Brand:** Simthread - **Colour:** 90wt Black - **Item length:** 274 Metres - **Item thickness:** 0.45 Inches - **Item weight:** 2.82 Ounces - **Manufacturer:** Simthread LLC - **Material:** Polyester - **Material composition:** polyester - **Product care instructions:** Hand Wash Only - **UPC:** 822360839379 ## Images ![Simthread 25pcs 90 Weight Black Prewound Bobbin Thread Size A Class 15 (SA156) with Clear Storage Plastic Case Box 60S/2 for Embroidery Thread Sewing Thread Machine DIY - Image 1](https://m.media-amazon.com/images/I/81tychbDN9L.jpg) ![Simthread 25pcs 90 Weight Black Prewound Bobbin Thread Size A Class 15 (SA156) with Clear Storage Plastic Case Box 60S/2 for Embroidery Thread Sewing Thread Machine DIY - Image 2](https://m.media-amazon.com/images/I/71ufXX4JsgL.jpg) ![Simthread 25pcs 90 Weight Black Prewound Bobbin Thread Size A Class 15 (SA156) with Clear Storage Plastic Case Box 60S/2 for Embroidery Thread Sewing Thread Machine DIY - Image 3](https://m.media-amazon.com/images/I/81viX0IPQlL.jpg) ![Simthread 25pcs 90 Weight Black Prewound Bobbin Thread Size A Class 15 (SA156) with Clear Storage Plastic Case Box 60S/2 for Embroidery Thread Sewing Thread Machine DIY - Image 4](https://m.media-amazon.com/images/I/716+CpG54vL.jpg) ![Simthread 25pcs 90 Weight Black Prewound Bobbin Thread Size A Class 15 (SA156) with Clear Storage Plastic Case Box 60S/2 for Embroidery Thread Sewing Thread Machine DIY - Image 5](https://m.media-amazon.com/images/I/81mj7acQlwL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good value and makes for easy and quick changes on projects *by S***E on 21 September 2020* I’ve used both the black and white bobbin threads in this little set and both stitched out great.
