USA Soft Mini (D-1) Ballpoint Refills, Medium Point, Blue, 4-Pack, High-Performance Refills for Multi-Function and Slim Pens

I bought these to replace the Zebra refill that arrives by default with a Livescribe Symphony pen. Length and thickness are the same. In comparison, these refills are *much* easier to write with—far more smooth feel, less rough paper feel, far less force required to write. Somewhat heavier line, I think these are a wider ink path than the default Zebra refill. But in any case—makes using the Livescribe Symphony pen far less tiring on the hand for extended periods of writing. Would recommend.

Got these for a livescribe aegir. Ordered the green and purple. Super happy with the purple color. Very bold bright color, even easier to read than black on grid paper (blue grid lines). I'm impressed with the softness of the feel - even softer and flowy than the Cross branded refills.

I purchased these refills to use with my Livescribe 2 GB Pulse Smartpen , which has notoriously bad OEM refills. It requires minimal hacking (literally cutting off the top quarter inch) to fit in the pen but the quality far exceeds Livescribe's own refills. Hopefully they last a while longer too.

I use these with a Livescribe 3 pen. They fit perfectly for me, I didn't have to modify the refills at all to use them as some others have reported. (I have the Livescribe 3 Black edition, not sure if that makes a difference...) Before switching to the Livescribe I used to write in gel ink exclusively, and I do not think these are really comparable to gel ink. But, of the ballpoint refill brands that I've tried so far (Livescribe, Cross, Schmidt) they are the smoothest to write with, so I will likely stick with these ones.

Smooth for writing and as an artist

Works very well. Comfortable to write with, nice smooth action with no leakage. Long lasting refill. Would definitely buy in the future.

I wanted to use this refill for my Livescribe Echo and needed to shave off a little bit of the end of this with a set of pliers. I also noticed that the refill would rattle inside the pen, so I added a small roll of transparent tape to the upper part of the refill and it helped a lot. This is a better writing refill than the Livescribe ones, but still not the best pen that I have written with. The refill does seem to run out of ink and then I shake it and it comes back. In spite of that, a 5 star purchase for the price and the value.

These pen ink refills are great. I bought them for two of my Lego pens that are long out of print and they fit perfectly. Alot of ink and it lasts a while.

A differenza delle cartucce originali della mia osama quadra, queste non scorrono ugualmente bene e l'inchiostro non viene rilasciato sempre in maniera corposa, spesso è necessario ripassare; alcune cartucce più di altre, perdendo anche inchiostro. Ho comprato 2 blister da 4, penso che terminato il secondo mi orienterò su qualcos'altro. PRO prezzo conveniente; venduto e spedito da amazon CONTRO alcune cartucce davvero scarse; altre solo discrete

Ho comprato queste cartucce come ricambio per una penna multifunzione. Non ne sono molto contenta perché la scrittura non è scorrevole, ho anche fatto fatica ad avviare l'unica che ho messo in funzione. In aggiunta, avverto quelli che, come me, si aspettano un colore arancione brillante, che questo qui è decisamente scuro e spento, poco distinguibile dal normale rosso. Io erroneamente pensavo ad un colore più simile all'arancione Bic che è più fluo e quindi utilizzabile come evidenziatore. In definitiva, consiglio di rivolgersi a marche più economiche.

En el título pone que es de color morado, pero en realidad el color de la tienta no le, es verde.

This refill while small fits exactly in the multi-tip pen it is designed for and works well
