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.

ThermoMaven Does All the Work and Eliminates All the Temp Worries
I made this purchase as a cost-effective way to monitor the meat temperature while cooking without any wires. I have used this in my smoker grill, traditional gas grill, charcoal grill, oven and rotisserie air fryer. I tested the reading for accuracy with other temp measuring devices and find that it has been spot on in every method. It is so easy to use that you push it into the meat to the designated line and it reads the ambient, (surrounding), temp as well as the current meat temp. The display is easy to read and has a backlight when cooking outdoors in dim lighting. It is magnetic so it keeps the controller in place. When finished easily clean the probe with dish detergent and a wipe. I will be purchasing the 4-probe version since I do a lot of smoker grill cooks so I can measure more than one zone or different foods at the same time.
