The pens shown here to test the foam holder are, in the first photo from L to R and in the second photo from top to bottom:
Pelikan 1000 Demonstrator
Visconti Opera (Black)
Noodlers Triple-Tail Demonstrator
Penlux Masterpiece Grand Daybreak (Red) FP
TWSBI Vac 700 (Amber Brown)
Bexley FP (Yellow)
Parker VP (Red w/ GF cap)
The Parker fits with some room to spare both lengthwise and widthwise. But the wider pens don't fit properly, especially when the lid is closed. With the lid closed, one could position pens with the clips sideways. I tried that, but doing so increases the width profile of the pen within each foam opening, so still more pens would not fit well. Yes, the foam has some give, but the real issue is the inadequate depth of the foam pen inserts. I wonder whether had the Case been a bit larger or, in the alternative, had each foam section been deeper and held 24 (rather than 30) pens (for a total of 48 for the entire Case), these problems would have been solved.
The lid, when closed, actually touches the pens and in some cases presses on them, even if one positions the pens sideways. A very bad situation. So, the lack of foam depth and the closeness of the lid to the foam sections, are problems. If one creates too much room between the lid and the pens, I fear that under carry conditions, the pens would come loose from their shallow foam inserts. So deeper foam would be preferred to an increase in the space between the lid and the pens in the foam. Perhaps PSI should try a bit of both, but that requires a larger Case.
It seems that medium-to-small pens that are of average width will fit well. If one uses only those pens with the Case, then the Case will work fine for display, storage, and carry. But these limiting conditions make this Case's practical use less than was hoped when I made the purchase. I'll keep the Case, though.
The Case costs $99.95 plus shipping. For my location, shipping costs $8.95, so my all-in cost was $108.90.
I read the reviews of this Case on the PSI site for this Case. 50 % of the reviews were 5-Star, and 50 % lower. When folks complain in giving 3 or less stars, they talk about in less detail what I've mentioned, or about the lack of durability of the Case in regular use.
I hope this review is helpful to those potentially considering this Case or who are looking for the best storage, carry, and display solutions for their pens, such as at pen shows.
