would this be reccomeded for autograph signing ? ive written books, and will be book signing soon.. so will they be good for that ?

These are great for getting photographs signed, unlike other brands there is no ink bleed even after years & even on inkjet photographs.

Is this suitable for touching in letters on a grave stone?

You take top marks for the most unusual question about a product that I have seen here. I have used Pentel marker pens for over 30 years in scientific and domestic situations, and they are very versatile, leaving a deep black mark, provided the pigment sticks on the surface. However, it contains a water-phobic solvent, so it may not be effective on damp surfaces - I know they won't mark damp glass- or plastic-ware. I might suggest acrylic paint instead, as that is water-based.

£3.64 for a pack of 12. Are you sure?

I can't remember buying these at this price (may have done) but can say it's very rare to have a problem through amazon. I am due to replace my stock so will be purchasing the myself. Best of luck

£3.64 for a pack of 12. Are you sure?

Bargain there normally £7 to £8 quality markers. I use them in the building game. Use on any surface the marker last for months.
