Lenses Technology:

✓ CR-39 Custom-Made Lenses

CR-39 is made by polymerization of diethyleneglycol bis allylcarbonate (ADC) in presence of diisopropyl peroxydicarbonate (IPP) initiator.
"CR-39" is an abbreviation of Columbia Resin 39. CR-39 has the highest Abbe value of any lens. An Abbe value defines the chromatic aberration of material, and this effect is generally more noticeable in peripheral vision than when looking through the center of a lens. Resin raw is injected into lenses mould. After that, the anti-scratch coating is applied.

  • Anti-scratch technology.
  • Unique colors, with over 4+ tests to achieve the final result.
  • Gradient colors with smooth transition.
  • All DE products have V-Groove (Removable Lenses - Technical feature that allows lenses to be removable, in order to add prescription etc)

+ Metal Parts.

Metal Core wire with IP plating that prevents oxidation and wear.

✓ 100% UV Protection.
The lenses we use, have a UV protective coating with maximum filtration against harmful sun rays.

✓ Lenses Category: 3.

The bigger the category number of lenses, the better. Category 3 in lenses, is considered better than categories 2 & 1. This is because they provide extra protection from both visible and UV light. These lenses allow less than 20% of visible light to penetrate the lens. This means that they will block out 80%+ of light. Category 3 lenses are considered some of the best lenses in the optical industry.

Acetate Technology:

✓ Italian (Mazzucchelli) Acetate.
Our Acetate Materials are coming from some of the biggest acetate factories in Europe. Fabricated from wood pulp and cotton.

Mazzucchelli 1849, is an Italian Company based in Castiglione Olona, and is a worldwide leader in the manufacturing and distribution of sheets made of Cellulose Acetate, polymer of natural origin, traditionally used in the production of optical and sunglass frames. Cellulose acetate is a modified natural polymer. To obtain Cellulose Acetate Mazzucchelli starts with the selection of renewable sources such as certain varieties of trees and cotton linters. From these sources the purest part of the cellulose is extracted which is subsequently treated with Acetic Anhydride and transformed into Cellulose Acetate powder.

✓ Engraved DE logo on the temples.
Every pair has the engraved logo, product name, and measurements on both temples.

Comes with a luxury box, eco-leather case, and cleaning cloth.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Great price great shoe
Size: 12, Color: Burgundy Polished Full Grain
Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.

Quality shoe but with a slight squeak.
Size: 10 Wide, Color: Burgundy Polished Full Grain
Nice shoes with the classic Penny Loafer design. Fit was better than another brand I tried. Only reason not 5 starts is disappointment due to a slight squeak at times when walking.

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.
