Your cart is empty.Enjoy the flexibility to switch between different thread and colors seamlessly with a set of 12 SINGER Class 15J Transparent Plastic Bobbins. These replacement plastic bobbins are a must-have addition to your sewing supplies, perfect for both novice and expert sewers. Class 15J bobbins are slightly curved and smaller than Class 15 bobbins, and should not be used interchangeably. They are commonly used in home sewing machines for various sewing projects, from simple repairs to complex garment construction. These versatile bobbins are compatible with select Singer Futura Embroidery Machines series 2600s, 3900s, 7400s, 8700s and Izek 1500 sewing machines. Please consult your machine’s manual to determine compatibility. In machine sewing, the bobbin thread forms the bottom part of your stitches, working with the top spool thread for strong, consistent stitches. Made from high-quality plastic, these bobbins ensure smooth thread winding and unwinding, preventing stitch irregularities and machine jamming. Using SINGER Bobbins is simple: wind your thread onto an empty bobbin, ensuring it is correctly seated in the bobbin winding tension disk of your machine. For best results, use bobbins that match the class/style of those that come with your machine and wind thread onto empty bobbins only, ensuring proper tension. Replace any bobbins that become chipped, bent, or damaged. Whether you're creating clothing, quilts, or DIY home décor, the pack of 12 SINGER Class 15J Transparent Bobbins delivers professional results with ease.

Not sure where the hold up was (I suspect UPS), but these got waylaid/held up and arrived a few days late. Since I believed it would be delivered on a day I had to work and was not given an option to choose my "Prime day", I opted to have it delivered to an Amazon locker about one mile away...only to have it end up coming on a day I was at home! So I could've skipped a trip to the locker site if I'd known. Annoying.Anyway, the bobbins work fine. I've got a fairly basic machine--an inexpensive Brother LS-2125i that I picked up at Walmart years ago when my antique Singer went kaput...it does what I need it to do (if not always as smoothly as I'd like). But I'm making quite a few masks for friends/family/self and needed more bobbins so I could get fancy and match thread colors to fabrics to make the masks look more professional and overall nicer.I ordered two sets and so far have used 8 of the first one. Both sets came in brand new condition so all good on that front. The bobbins do fit my machine, unlike the size 15 I bought at a store prior to these (not realizing that "15" was NOT the same as "15J"). They wind without breaking and generally appear to be good quality.One thing I did notice is that they must be just a trifle thicker/different than the original bobbins that came with my machine. The tension on my sewing suddenly changed--it took a bit of trouble shooting to get that figured out-- and I do hear a bit of noise from the bobbin area as I sew, as if the bobbin is rubbing a bit at times. The metal bobbin case (that the plastic bobbin fits into) has an adjustment screw, so I will monkey with that to see if that helps. The machine still sews and I was able to get through my last batch of masks--I'm actually using a serger for a majority of seams--but appears to need some fine tuning for these new bobbins if I'm going to do more than a few inches here & there.No regrets in choosing this product, they do indeed fill my need for 15J bobbins, and the spot of weirdness with the tension prompted me to learn a bit more about my machine--not a bad thing, just be patient and use Google, lol!

Who knew bobbins came in different sizes? They all look basically the same to me.I was having trouble with the zigzag on my Singer One machine. I got the manual out, cleaned the bobbin area, then went through the manual page by page to see what my problem was.When I came to the section on bobbins, I saw that my machine needed a Class 15J Bobbin to work at its best. I purchased these bobbins immediately. When they arrived, I put them to the test. Low and behold my machine is running properly, and I can use my zigzag!

Bobbins were ordered for my Singer Patchwork sewing machine according to the machine's manual. Disappointed that the container to store the bobbins didn't make the trip in one piece. One of the tabs in the back that holds the top on was broken during transit.

They work great in my singer heavy duty. It's also a bonus that they comes with a handy little storage container! I will definitely be reusing that for all my bobbins! Great value for the money!

This is the exact kind of bobbins I need for my machine. Glad I was able to get them so quickly.

As bobinas (carretilhas, canelinhas, ou outro nome como você expressa esse produto) da Singer são as melhores que já usei e faço questão de comprá-las. O motivo é que são de material superior das genéricas importadas pois não trincam ou quebram com facilidade e também o encaixe delas na máquina se faz de forma suave e precisa. Eu as escolho por serem econômicas (duram mais) e preservam a máquina de costura.

Trop cher pour le nombre de canettes, sinon parfait pour ma singer. Je me suis séparée de toutes les canettes universelles pour prendre le bon modèle conseillé dans le mode d’emploi de ma machine.
