With this center finder, you can easily mark the center of different things without measuring. Saves time and comes in handy for DIY stuff where you don’t need perfect accuracy.

How to use it:

• place center finder on top of object
• align both sides with the edges of the object
• draw line through the middle onto the object
• repeat at a different angle
• mark the center

It’s got a 2 mm gap in the middle which is wide enough to fit fine liners and ball pens through while still staying more or less accurate.
