Great mechanical pencil
This is the solution to crooked lines if you draw with a mechanical pencil. Not to mention less breaking leads.

Uni stationary stuff are always the best

Very good pencil but too light
The pencil writes and draws very well. It stays sharp and the lead does not break easily. The only think I don't like about it is it's too light. It would be better if it was a little weighted / heavier.

Very comfortable. The mateal tip can go in completelly, protected by the plastic. Excellent in my opinion!

A distanza di un anno dell’acquisto posso sinceramente affermare che è la mia matita preferita! Sono anni che uso le matite meccaniche e una cosa che ho sempre odiato è proprio i differenti tratti che inevitabilmente si vengono a creare quando la mina viene utilizzata. Questa matita invece, grazie al minuscolo meccanismo che ha al suo interno, ruota la mina ogni volta che questa viene sollevata dal foglio, così che il tratto sia sempre omogeneo (come si può vedere dal video, il piccolo disegno bianco che ruota). La consiglio davvero a tutti, è un piccolo luxury che migliora le giornate!

It doesn't write comfortably as the metal part keeps moving and going in

The uni kuru toga pipe slide is way better than those low quality plastic ones - this one is great quality, feels great to hold. The design is beautiful, I love how the mechanism looks, the turning mechanism is really nice to write and sketch with. The pipe slide model has the W Speed engine, which means the turning mechanism is 2x the speed of the standard model, and there is a massive difference! Another pro is the 0.5mm lead - way better than 0.7 or 0.9 in my opinion, the sharp 0.5mm paired with the turning mechanism gives amazing handwring results. And it has worked with many different brands of lead.

Writing looks uniform and the lead doesn't worn down on one side due to the mechanism that rotates the lead while writing.
