Is this pen refillable?
Thank you for your enquiry.
The Pebeo Drawing Gum pen is not refillable.
Hello. I have bought both 0.7 & 4 mm pens. Do I need to fill them with the masking fluid first? Non of them is working. If I need to fill them, how should I do that as I can not open them. Thanks
Both of these pens are prefilled with masking fluid. The 0.7 is a latex solution and the 4mm is a non-latex, synthetic version.
You need to activate these pens by shaking gently and then depressing or pumping the nib until the masking fluid runs down into the nib. The 0.7 is a very pale blue and can be sometimes be difficult to see when applied to the paper. It does dry darker, so it can be seen when you apply colour.
I hope this helps.
