Pen & Ink Felt Tip Crayon Ballpoint Stain Remover Cleaner Stain Devils - Citystores

It said it doesn't remove black biro but that isn't true it completely removed every trace of biro. Recommend this product and there is still lots left for another 2 or 3 uses

I bought this as I had pen on my leather couch but read that it doesn't work on leather. Never mind it will be useful to keep.

Best stain remover I've used for getting biro out of my nephews nursing uniform his mum had tried other stain removers they did nothing this truly works.

Dosnt work

Great it works amazing on wood but still hard to get rid of stubborn stains on fabric

This is a miracle worker on most pen stains, has worked well on biro and felt tips, however doesn’t fully get rid of white board marker marks

It didn't do the job

Once I left the stain remover on my leather jacket over a few hours it removed very dark black ink from a light grey leather jacket. Definitely recommend it works just give it time
