Q:
"Hello. A pen is empty, although I haven't even used the first tip yet. The other pen was empty after the 4th refill."

A:
"Hello, was the marker correctly pierced when first used and shaken before? In rare cases the mine does not work right away. Before using the pen for the first time, you should repeatedly press down the joint marker with the tip several times to "pump" the pen. How exactly can be seen on the pictures on the back of the blister pack. You should then give the tip a little time before using it for the first time so that it can soak up sufficiently."

Q:
"How many meters does the pen last for?"

A:
"Hello, unfortunately this cannot be said so sweepingly.
The range of the marker is primarily dependent on how wide the joints are and how often you have to re-touch them with the marker. The surface of the joint also plays a role, as a coarse or rough structure of the joint absorbs more colour than a smooth one. The marker comes with three writing tips to replace the felt pen tip, which can be used for heavy duty in very rough joints. We also offer replacement tips for subsequent purchase. "

Q:
"I unpacked the blister some time ago and can't remember where I put the tips and can't use the marker without it. Do I have to order a new pencil now?"

A:
Hello. no, you don't have to. You can also use the replacement tips for the edding 750 paint marker as a matching tip. The tips supplied with the joint marker are therefore identical. These are the edding 4-750N tips.
