Because this calendar is designed to be used with dry erase markers, accidentally rubbing your hand on an entry can smudge or wipe away the writing. Previous writing may also blur if left to remain on a month’s page while moving on to future months.
We recommend using a standard oil-based marker when writing important and certain dates you don’t want to erase, such as birthdays and anniversaries.

Using markers with water-based ink, such as wet erase markers, will cause the ink to take a very long time to dry. Once the ink dries, it will be difficult to erase. Avoid using these types of markers.

The whiteboard paper in this calendar is weak to heat. Avoid storing it in bathrooms or other rooms prone to becoming warm.
We have also confirmed that the marker pen can be affected by high temperature and humidity, and in rare cases, the ink may become permanent if left in such conditions for several days after writing. We appreciate your understanding and hope you can use the product with this in mind.

Do not store the marker straight up or down, as it causes the ink to collect and stop coming out. We recommend storing the marker horizontally flat. In addition, ink may be difficult to dispense at first depending on the positioning of the products in the packaged set. If ink starts out difficult to dispense, leave the marker down flat in a horizontal position for a while before trying again.

If the bottom of the pen starts to drop downward after placing the pen horizontally against the magnet, tightly squeeze the magnet on the pen cap with your finger. These adhesive magnet strips have been applied to the pen caps by hand, so they may not be exactly even. Squeezing the magnet back against the pen cap helps flatten the magnet strip and strengthen the magnetic pull.

The adhesive metal bar included with the Full Size and Medium Size calendars can be applied wherever you like such as atop the calendar. The metal bar is intended to provide a spot for you to store your dry erase marker by the magnet on the pen cap. You can also use your own magnet to store receipts and notes on this spot.

*Items stored here by a magnet have the possibility of getting lost, so we do not recommend storing especially important receipts or tickets.
*Metal bar is made of tin. Tightly squeezing the bar and its edges or rubbing the edges against your hands may result in injury. Please handle with care.
Keep out of reach of children.
