For a custom Moscow Mule mug, settle the construction first, then choose the finish and the logo method as one decision and approve both on a sample in the final finish. The same logo method gives a different result on copper plating and on bare stainless steel: a laser that strips a plated layer shows the metal underneath, while on bare steel it recolors or engraves the surface itself. A logo approved on a photo, or on a different finish, tells you little.
Buyers will meet three constructions: solid copper, stainless steel with a copper-plated exterior, and stainless steel in another finish. What matters most is what touches the drink. The FDA Food Code (section 4-101.14), a model code that state and local jurisdictions adopt, bars copper and copper alloys from contact with foods below pH 6, such as fruit juice. Some solid copper brands, such as Copper Mug Co., leave the interior raw copper and lacquer only the outside.
We make stainless steel Moscow Mule mugs only, with a 304 stainless steel body, such as our copper-plated stainless steel Moscow Mule mug. The copper color is electroplated. The rim and interior can be plated in the same color or left as bare 304 stainless steel, as the order specifies, so treat the interior as its own line on the spec sheet. If you want it plated, check the plating against the food-contact rules of your market. For which material to choose in the first place, see copper vs stainless steel Moscow Mule mugs.

Our Moscow Mule mugs come in copper plating, gold plating, rainbow plating, other colored finishes and etched artwork, on smooth, hammered, diamond-textured or pineapple-textured bodies. When you specify the surface, cover four details:

The finish decides how each logo method marks the mug and what color the mark takes. Trotec Laser describes three ways a laser marks metal: annealing recolors the metal with low heat and leaves the surface smooth, engraving vaporizes material and leaves a slight depression, and on coated metal the laser removes the top layer.
On our mugs, that is the difference between the two surfaces. On copper-plated steel the laser strips plating, so the logo shows silver, gray or dark depending on which layer it reaches. On bare stainless steel it marks the metal itself. Etching cuts into the surface, and deep etching after the final plating can break the plating, so etched artwork is planned before the mug is plated. Silk printing and decals sit on top of either base and add color. Embossing and debossing shape the metal and keep the mug's color. For the trade-offs between logo methods across barware, see which logo method works best for custom barware.

What each method looks like on the two surfaces we make:
| Logo method | On copper-plated stainless steel | On bare stainless steel |
|---|---|---|
| Laser | Silver, gray or dark logo, depending on which layer is removed | Black-gray mark, or a light gray matte engraved mark |
| Etching | Recessed logo; deep etching after the final plating can break the plating and is not recommended | Shallow recessed matte gray mark, can be filled black |
| Silk printing | Black, white or a specified color on the copper-colored base | Black, white or a specified color on the silver base |
| Decal | Full-color artwork, copper-colored base kept | Full-color artwork, stainless base kept |
| Embossing | Raised logo, the whole mug stays copper-colored | Silver raised logo |
| Debossing | Recessed logo, the whole mug stays copper-colored | Silver recessed logo |

Approve a sample in the final finish with the final logo on it, not a blank mug or a photo. Check four things before bulk production:

To quote a custom Moscow Mule mug, we need:
For an existing model with a custom finish and logo, the MOQ is 100 pcs, samples take 3–7 days and bulk production 25–35 days; new tooling is quoted separately. Send your spec and logo file to our OEM and customization team, and we will make the first sample in the final finish with your logo applied.
