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.

Great Vest
this golf vest is amazing. It’s very well-made. It fits well, I’m a double X and I’m 62 and a slice of pizza from 230 pounds. I just love it and plan to buy more. I believe it’s gonna wear very well, but I’ll let you all know in a month or two after I’ve worn it a couple times and washed it a couple times.

As Advertised!
Product arrived promptly & well-packaged (shrink wrapped packaged & enclosed inside additional box). Golf vest was received "as advertised" & appears to be of good quality. Vest was fairly priced & is very comfy, lightweight, stylish & wrinkle resistant. Purchased as a gift for my adult son for his future golf adventures. Size/fit will need to be determined by my son when he prepares for his next golf outing. Very pleased with my purchase & will consider additional purchases from seller in the future.

Great vest
Color: Dark Grey, Size: X-Large
This lil vest is awesome. A little thicker than I expected but perfect for my cool office. Looks like it cost twice as much. I had my company info put on it and looks like it cost 150.
