Dust-free

There is no dust at all. The teaching board is absolutely clean without any residue with the use of Water-based Environmental Teaching Pen and Cleaning Water. It guarantees a free from chalk dust teaching environment and puts an end to teachers’ occupational disease caused by chalk dust.

Nontoxic

The main content of the ink is pure water which has passed relevant international tests, for example, SGS∙ROHS certification, American Safety Standards of ASTM F963-08, test for phthalates, European Union Toy Safety Standards of EN71 part3. It is 100% nontoxic.

Nonflammable

Whiteboard markers are not allowed to be stored and transported in large quantities because their solvent is inflammable. It is a potential safety hazard when they are stored in schools. Our Water-based Environmental Teaching Ink is nonflammable because the solvent is pure water.

Refillable

When the pen runs out of ink, it can be refilled within a few seconds. You can write 6000 to 8000 words with each refill and 80000 to 10000 words with each bottle of ink. The tip of the pen is dry-resistant. It won’t dry out with the cap opened for three to five days.

Low-cost

The average cost for a typical classroom use is RMB50 per semester. A substantial cost reduction for our customers.
