Printed silicone one colour keyrings have your logo/message/ event printed onto the surface of the silicone part of the keyring.
Printed keyrings are a great choice for the more complicated design or logo. The fine printing ability means that you can print virtually anything on these keyrings.
This method of printing is not as durable as debossed filled. Inks and bands come in a wide range of colours with the additional glitter option.
