“The black stamp is great. The white is difficult to use on clothing, even really dark colours that offer high contrast - but works perfectly on water bottles, lunch boxes, shoes etc. I find in practice it's a lot harder to find a good spot to stamp on clothing than the videos show due to pull cords, sewn-in elastic, ribbed collars etc. However it is crystal clear on tags and wherever you can find a thick flat spot. Will see how well the ink stands up to regular washing.”
