We are delighted to announce the launch of the highly anticipated S.T. Dupont 'Diamond Guilloche' collection for 2020, a luxurious series of fine writing instruments created exclusively for the US market.
This new collection combines old world Dupont glamour with an updated modern design. S.T. Dupont brings together one of their oldest and most treasured crafting techniques 'guilloche under lacquer' to the newly updated large size 'Line D'. Available in 3 vibrant colors: Ruby, Sapphire and Aquamarine, the pens combine the skills of the S.T. Dupont master goldsmith with the expertise of their master lacquerer.
Diamond 'Guilloche'
The 'Diamond Guilloche' collection features the namesake technique that is French for "engine turning." The diamond design is created by an engine turning process that engraves very precise, intricate, geometric patterns into an underlying material. For this latest launch, S.T. Dupont selected a finely detailed diamond pattern which is then overlaid with sumptuously colored Urushi lacquer, the result is simply spectacular.
Urushi Lacquer
S.T. Dupont's artisans add layers of natural lacquer to the surface of the diamond patterned guilloche in a months long process involving many applications and polishing to impart depth and mystery to each finish. The engraving causes the reflection of light through the overlay of natural Urushi lacquer creating a stunning display of light and color.
Line D Large
The collection is launched on the newly updated Line D Large pen; recently remodeled with a new bold blazon on the articulated clip, an enhanced Dupont 'D' in the crown of the cap and a perfectly balanced shape for exceptional writing. The pen cap closes with Dupont's iconic 'cling' and features a fluted grip section for a superb writing experience.

It's a Filter!
Size: 97133L1000&28113AA100
Fit great! Just look on youtube how to put in! I'm not in a particularly dusty area, but the air cabin filter was a disaster after only a year. Will buy again!

Easy
Size: CF11966&CA12166
Perfect fit. Easy to install. Good price. When changing the cabin filter the screw removal is a little easier if you notch out the plastic in front of it. Its behind the glove box and is not noticeable.

INFISTAR AC85111 Cabin Air Filter
Perfect fit! So grateful for you carrying this and the great price. My AC has been out for about a year but when I replaced this, it now works again! Had no idea there was such a thing.
