Exactly what I was looking for

I bought these in April 2022 and it’s now dec 2023 and I just swapped it out for the second pair. I probs could’ve done it a bit earlier but the first set really just lasted that long without many problems. I honestly forgot that I bought a two pack at first because I haven’t changed it since. I wanna say though that it’s super important to change out your blades when you start to notice them not cutting as sharply. If you don’t, it can cause problems since the fabric may not get cut, get fed through to the needles and loopers, and get stuck. If you have a brother 1034d, you may know that the timing of the loopers gets set off quite often since the machine is made cheaply. So, to prevent that, changing out the blades is important. Along with cleaning and oiling regularly :)
