It might be a price mistake, but seller MaxWarehouse on Amazon is selling 24-count of medium sized Paper Mate Pink Pearl erasers for $3.68 (was $15.99). It’s not prime shipping, but it’s free shipping. It might take a couple of weeks to arrive, but it’s great for kids or teachers next school year.
I don’t know what the quality is like, but it gets good reviews on Amazon.
