I didn't get this eraser off of JetPens specifically, but I have tried it out and it works quite nicely. This thing is quite popular and hard to obtain at the time I'm writing this.

There hasn't really been a proper transparent eraser prior to the Clear Radar, so if you go with a clear acrylic stationery look, this eraser goes very nicely with it. I'd imagine it was hard to come up with a formula that can erase without much dust and still be transparent, so kudos to Seed.

Once you get rid of the white dust that covers the eraser(this can be done with a touch of water), it looks much more clear and you can really see any text you put the eraser over. I do have to say that it does have to smudge pencil lead first before properly erasing it, so it may feel awkward and is not the most practical eraser compared to say, Matomaru-kun or the Rabbit W Foam Eraser for example. That is to say though that this eraser is moreso made for aesthetic purposes and can still function as a very basic eraser.

I wanted to like this eraser so much, but I found that it smeared my pencil markings all too often, and made them even more impossible to erase, ironically. The Tombow Mono erasers are my long distance partner, and I regret the infidelity. However, I did enjoy this Seed Clear Radar 100 eraser's style and shape!

just got mine and i was excited but i erased and it smears so badly. it has a nice look and if you erase for a while it will erase just fine but it smears the heck out of what you're erasing. dont recommend.

It’s more of a novelty eraser. It doesn’t work as well as most of the erasers on the site but it does work if you push down really hard.

They look so cool, but don't erase very well due to smudging. Alright if you just want a neat looking eraser, but not so much for functionality.
