  • Easy to use; works in my oldish Kenmore
Color: Transparent Size: Single
It is so nice to have pre-wound bobbins. So far, I have only used one color, but it is working perfectly without issue. I have a Kenmore 365-16231 purchased around 2008 time frame, almost never used, just serviced in April 2026 - so it is like a brand new machine. (the machine manufacturer is Janome; the size is compatible with Janome 15 bobbins). I am not sure these plastic bobbins will work in vintage machines that take metal bobbins, they might be too lightweight. I chose pre-wound bobbins instead of empty spare bobbins with the intention of reusing the bobbins once they are empty. The bobbins appear to be a sturdy enough to withstand re-winding once empty. I am pleased with my purchase and would consider a repurchase as a timesaving option (though this would create unnecessary plastic waste & I don't know what I'd do with all the extra empty bobbins). ... show more

  • The Perfect Size for My Small Sewing Basket
Color: Transparent Size: Single
I bought 2 Threaded Bobbin Packs, since the pencil case-sized emergency sewing repair kit at my children's house also needed a selection of colored threads. I couldn't find the dimensions of the bobbins case here or on the internet, but the received bobbins case measures 3-3/16" L x 2-1/8" W x 1" H.
