20Pk Magic Eraser Extra Thick Sponges

Decent price, but do be aware these are not brand name “Magic Eraser”, which, IIRC is also a registered trademark of Proctor and Gamble. The photos even mention that these are thicker than the “leading brand”.

Previous deal was a bit better. These can be had for $11.95 with free prime shipping on the mothership

These are a good add-on purchase, if you’ve already spent your $5 for shipping.
