Delivery was prompt, price was good for product and the fluid does a good job of keeping pen nib clean. Purchased previously and still excellent product.

Cleaned the ink out of the fins in my fountain pens very quickly without effort. Even the fine shimmery bits.

Rapido-Eze Cleans EVERYTHING! From ultrasonic to let it sit and get clean, Rapido-Eze will clean the smallest 6x0 pen nibs to the largest 4. Highly recommended!
