r/erasers

I'm looking for alternatives besides Amazon. Online stores, teacher supply shops, craft stores, dollar stores, stationery shops...I'd love to hear everyone's favorite places to buy erasers and why. Bonus points if they have cute or unique designs! 😊

I recently bought a couple of Koh-I-Noor kneaded erasers (I was putting in an order for other things and got them on a whim). Trying one out, it bent in half, then sprang back into it's original shape. I figured it just needed to be warmed up and worked a bit (it's the middle of winter where I am) and proceeded to warm it up and kneed it for a while. It did soften up, but it went back to its too-firm state.

Questions:

This was Koh-I-Noor Artist Putty Eraser, has anyone used or had problems with this product?

Is there anyway to revive a kneaded eraser that's dried out? I've seen something that says to knead a few drops of water into it, but it seems fairly waterproof.
