Will this fit Janome 2212?

So these are standard class 15 bobbin cases. They measure about 22.75mm across. The majority of front-loading machines can take this case, a few won't. It's hard to tell whether or not yours can fit it because the difference is 1-3 mm, which is tiny. Most accurate way I've found to test: measure your actual bobbin size. It should be 20.3mm across and 11.7mm wide. If it's smaller than that, it's not a model 15 so these will not work. Hope that helps.

quality product but didn't fit my machine.

Very good quality, however they did not fit my machine. My fault since I thought they all were the same size.

Ask Rufus if Bobbin case if it fits your machine

It said it fits most...Make sure to ask Rufus if it fits your exact machine. My machine kept coming unthreaded, bunching up..., I put in new needle, new spool of thread, new bobbin. Turns out it was just the wrong bobbin case.

What can I say? I like to have spare parts handy just in case. Also, if you sew stretch knits with woolly nylon on the bobbin, it is very handy to have a case with low tension for your WN and another with normal tension for normal thread, so you don't have to keep mucking around with your screwdriver and hoping you've got it adjusted right.

Well and accurately made, worked a treat in my Taiwan manufactured Singer 5522. Great value as completely dispelled my doubts about quality given the price. Highly recommended.
