I don’t know. I support the “no sticker gang” movement, but in this case, since they have their own box and lead case, I think it’s better to keep the stickers.
Is the PG2003 your favorite? What is your favorite amongst all your MPs?
There isn’t any other holder as long as that is that is balanced so perfectly! (That I’ve held)
Looks like a dip pen without the nib
Thank you
That’s correct. It’s a dip pen/nib holder. One would insert a steel nib into it for dipping into ink to write with, like a fountain pen without a reservoir.

Perfection?
I like bellows
I suggest using “accordion” for those with a rounded tip and “bellows” fot the flat-tipped ones. Or vice-versa, as you prefer.
Although it’s arguable if SMASH was the first to have this style of button, I think it is the most popular and well documented example, with lots of design-related (in Japanese) articles online. I used ‘accordion sleeve’ in my own notes but it seems Pentel officially used ‘bellows’ in some of their published articles. Here are some I bookmarked:
Pentel Official Blog entry for the SMASH. Excerpts:
A “knock button” that makes you want to press it
The knock button is just as unique as the rubber ribs. The knock button on the Smash is covered with a bellows that looks just like a pump. The design intent was to create a sense of unity with the entire body. To bring out the toughness of the concept, the design was inspired by the shock absorbers found on motorcycles. It’s very entertaining to watch the bellows compress when you press the knock button.
Pentel Mechanical Pencil Research Club interview with Pentel team on the 2019 update to the SMASH line-up. Some excerpts:
"Based on the results of user surveys, the product concept for Smash was “a tough and reliable mechanical pencil for active students and working adults for whom writing with a mechanical pencil or lead pencil is a part of their daily lives.” And the selling point, expressed in one word, was set as “having the tough functionality for heavy writing.”
Thank you, Kelvin!
According to the German publication “Die neuen Schreibstifte in der DDR 1977 bis 1988” (The new writing pens in the GDR from 1977 to 1988, published by Richard Anger in 2020) the corrugated rubber collar at the movable part belonged to a pen design created in 1979 by a collective of four designers, together with a wire clip (the one on the LAMY safari, which came onto the market the following year, was very similar).
So good! The two on the left are hard to come by (especially in working condition, as they often have slippery clutches).
That BOXY is unreal! Never seen it before ![]()
