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.

Got the job done!
Size: 5 FT (2 prong plug), Color: White
This was the perfect solution. Old outlet and the single plug didn’t overly strain the wall socket. Lots of plug-ins for all our electronics and a long enough core to reach them all.

Lots of nice features
Size: 5 FT (2 prong plug), Color: White
664Very nice. Even the slots on the sides will enable a larger than expected plug. Wish they included the screws for mounting. Didn't think it would be a big deal as I always keep the extras from projects, but it would have been a nice touch. If you do mount the power strip, it does reduce the size of the plug it will accommodate on the sides. Also wish I would have purchased the longer cord- NOT the fault of the product. Love the flat angled plug! I'm using it behind an adjustable bed frame that moves several times a night, so knowing I won't accidentally knock it out of the wall is nice. And you can easily use both wall plugs. Also very convenient to connect the USB & USB-c plugs without the bricks.

Works perfectly for what I needed
Size: 5 FT (2 prong plug), Color: White
We have an older house and I needed a 3 prong plug in our living room and this has absolutely done the job. I love that I can now plug my computer in and as a bonus, I can charge my phone if needed. The cord link is longer than I needed for the living room but worked great for a recent trip.

GOOD VALUE/GOOD PRODUCT
Size: 5 FT (2 prong plug), Color: White
FINE. HOWEVER YOU BETTER UNDERSTAND HOW MANY WATTS EACH DEVICE IS PULLING IF YOU TRY TO USE ALL 12 AC OUTLETS. GOOD VALUE
