The new design has features which make the stamp more ergonomic, such as the grip zone for a better handling, the bigger and smoother wheels for a comfortable date setting with clean fingers and a flat head for an easy text plate mounting in the case of the 4850. All of these of course while improving the core characteristics that makes this stamp so popular: a small stamp with a strong base plate promising durability and a very long lifetime.
The replacement cartridges are well known and continue as in the past: Compatible are 6/4910 and 6/4850. The 6/4850/2 is optional for a 2-color impression with a blue impression and red highlighted date.
This stamp uses the Trodat 4850 and can have your own custom text made for it.
