Rhodium Pen Plating Solution Watch Our Video

Our rhodium pen plating solution plates bright and white. One of the reasons for this is that it is free from additives whose breakdown products can cause darkening of the plate and reduce shelf life.

Please use our Fibre Nibs with our rhodium pen solution and these can be purchased HERE

This solution has an extra long shelf life of over 5 years.

Rhodium content: 20 grams per litre.

Our Palladium Pen Plating Solution is a good alternative to rhodium and can be shipped outside the UK and EU.
