E16. Black Pentel Clic Eraser Refill Ink Eraser.
One Black Refill for Pentel Cliceraser ZE33 For erasing ink from paper. The narrow size makes it ideal for corrections. It is gritty and works for tough corrections but is surprisingly gentle on paper. A neat, well designed tool. Highly sought after, but almost impossible to find in the USA. (This eraser is NOT for erasing pencil guidelines. For that, use E08. Factis Black Eraser or E22. Tombow Mono Zero.) This is the REFILL.
For the Black Pentel Clic Eraser, E15.
