  1. When a lead residue remains on the nib.

    There may be a lead residue being left in the chuck of the Mechanism

    Please remove the residue out of Chuck.

  2.  When the lead is stuck in the chuck of the mechanical pencil.

    If you remove the metal cone by unscrewing, there is chuck inside of the main body, the lead may be clogged into the chuck inside the mechanical pencil as shown in the photo below.

    The clogged lead should be removed. Take out the whole unit of rear end with clip. You will see the lead chamber (tube) inside, please put the new lead in to the lead chamber. Assemble back the rear end unit. Please give push actions to the rear end approx. 10 times to advancing the lead. (This is necessary for lead to reach to the chucking mechanism until the top of the lead to appear from the tip.

Please look at movie from this link.

We have Trio ( multi function pencil ) with two color pencil + tracer and Trio colors ( 3 color pencils)

  1. First of all, all lead residues inside of transparent chamber need to be taken out.
     ( you can use your needle to clean inside the tip.)
  2. Secondly, please put one lead to the transparent tube from the top not from the tip.
    Then, move the tip a little bit, then, the lead will fall into the chucking system ( the lead will not play inside of chamber. )  You can see the movie how to refill the lead in our web site.
  3. Then, this is very important to put inside of the mechanism hole firmly. If the tube mechanism put it back loosely, you may have trouble to rotating mechanism when you assemble the front barrel to rear one.
  4. Please do not force to rotate the barrel when you feel some resistance. If you do it, then, the mechanism inside will be broken. ( please be careful.)

Please do not spray on your fabrics and iron it before erasing the marked line.

It makes the line stay.

Please wash the fabric gently. The marked line was very week against the sun light.

It may fade the line with the strong sun light.

But, if you still the line, we recommend you to use the our stain maid.

This product is made by the pure natural orange oil and it make the line off easily.

But, it is totally depend on your fabrics. Some fabrics are not so easy to erase it if you spray it.

Please make the test on your unused fabrics first.
