Custom Iron Flask Tumblers

Which Iron Flask tumbler should you choose?

The Classic Tumbler 2.0 and the Rover 2.0 are both 24 oz with two lids and a rubber base that keeps them quiet and non-slip. The Rover 2.0 is rated a little longer for cold drinks (18 hours against 16) and has a built-in coaster. The Nomad is the smaller 20 oz option with a splash-proof straw lid and a flip lid, and the 40 oz Travel Tumbler adds a stainless steel straw lid for long days.

Gradient versions come in two-tone fade colors such as Day & Night and Cotton Candy; their lids differ from the 2.0 models, and the guide lists what each one includes. All of them fit most cup holders and ship in a gift box, which saves a step when they are handed out as gifts.

Engraving, minimums and production

Your logo is laser engraved, which removes the powder coat and shows the stainless steel underneath, so it comes out in one metallic tone and cannot peel or wash off. The engraving area is about 2.3" x 2.4" on the Rover and up to 2.4" x 3" on the Classic, with a wider wrap-style area on some models. Minimums are 20 or 24 pieces for most tumblers and 12 for the 40 oz Travel Tumbler, and production takes about ten business days after proof approval.

Something to know before you order

Iron Flask recommends hand washing in warm soapy water, not the dishwasher. If the tumblers are going to an office kitchen, it is worth saying so on the card that goes with them.
