1. 17oz Stainless Steel Mug

This 17 oz stainless steel mug is our best-selling natural-finish stainless steel blank. Compared with regular ceramic mugs, it’s sturdier and more resistant to breakage. Its double-wall vacuum insulation keeps drinks hot or cold for longer. It’s practical, too, and makes a great canvas for customization. The uncoated stainless steel surface gives you plenty of creative freedom. You can spray-paint it in different colors, decorate it with epoxy resin, or customize it with vinyl stickers or UV DTF transfers.

This mug is suitable for frequent use at home, on campus, or at the office. Once customized, it’s ready for everyday use or makes a thoughtful gift. Its versatility also creates more opportunities for custom businesses. With plenty of room for different designs, this 17oz stainless steel mug makes it easy to take on a variety of custom orders.

2. 20oz Stainless Steel Skinny Tumbler with Handle

This is the handled version of our skinny stainless steel tumbler, featuring an integrated handle that makes it easier to hold and carry. Compared with the 17oz mug in the same series, the 20oz version offers a larger area for customization. It’s well-made, with a smooth, simple stainless steel surface that works with a variety of customization techniques.

Take epoxy resin crafts as an example. The straight, slim body is easier to work with, and crafters can mix different colors, textures, and decorative styles to create glitter tumblers, marble-effect designs, and more. Want to learn more?

Each case comes with an assortment of colors, so you can choose a suitable base color for your design and create a laser-engraved tumbler with a coordinated look.
