Q & A

Q: Will the printed math problems be repeated?

A: The seal can print ten math problems by turning one circle, and needs to be adjusted after one circle, otherwise there will be duplicate questions. It is recommended that the four seals be used alternately to enrich the question types.

Q: Will the ink spill?

A: The ink bottle is airtight and will not leak. We recommend closing the cap of the bottle in time when the ink is not in use to prevent the ink from drying out. A small amount of ink on the printing paper is normal and does not affect the writing effect.

Q: What do these stamps do?

A: Our Math Roller Stamp is not only convenient and fast, but also can cultivate children's logical calculation ability and improve the speed and accuracy of oral calculation. Strengthen the bond between parent/teacher and child.
