OHPen universal - Pen for Overhead Projection - Permanent Fine (F) - Pack of 10 - Black

Have used these forever - would be lost without them - Nice clear line

Nice sized tip and has very good staying power

Great

Just what I was looking for

Useful.

Very good for wife who has Macula

Bit of a ronseal product. Does exactly as described.

I find these excellent for jobs like addressing letters and parcels where it is important that they do not smear if the weather is wet, and I will happily use them for most writing if no cheaper pen is to hand. They are easy and light to hold, and I like to always keep a stock of them. I have used both the Fine and, for writing in a small space, e.g. on labels, the Superfine.
