4PCS Smart Math Roller Stamps,Teaching Stamps for Kids,Math Practice Stamps,Addition Subtraction Multiplication Division Math Learning Stamps Within 100,for Preschool Kindergarten Classroom Supplies.

These roll well, show well and kids love to use them. It really does help with making math fun! Thanks!

My third grader is always asking me to print sheets for his math; this saves so much ink and paper out of my printer!! Super simple and convenient!!!

Bought these as a stocking stuffer for my math obsessed kids. It was alot of fun! They now add math equations to their normal drawings. Giving four stars though because the ink came cracked and it was a pain to clean up out of the bag.

Good

Super cute but the ink exploded all over before I received my package

It's very practical to print several pages of exercises and include that as part of homework. That habit improves considerably math skills.

They should have also come with information that they were already full of ink. Perhaps they would not have leaked ink all over.

The media could not be loaded.  All 4 arrived in good condition with no ink leaks. Easy to add ink. Easy to change combination of numbers. Fun way to do math with kids. Easy for kids to do on their own. I’m happy with this purchase.

Not Good

Nice

When these arrived I took them out of their case and they immediately leaked ink all over my hands. They also only print about ten equations until they loop and need to be clicked on manually.

The advertisement shows lower numbers (suitable for a 6/7yo), but the actual product is for kids much older. Pity there aren’t lower numbers within the packet.
