What 8oz Actually Means in Practice
An 8oz flask is rated at 8 US fluid ounces, or approximately 237 ml. In practical terms that is about five 1.5oz pours, or a little under half a standard 750 ml bottle.
Two caveats apply to every supplier, ours included. First, usable capacity is slightly lower than nominal because you must leave headroom for the cap and for liquid expansion. Expect to fill to roughly 90 to 95 percent of the stated figure. Second, flask sizes are often labeled in ounces but measured in millilitres during production, so a nominal 8oz body may read 230 to 240 ml on the line.
For buyers, the practical takeaway is to specify the fill volume you want your customer to see, not just the label. If your retail packaging claims 8oz, confirm the measured capacity with your supplier before printing cartons.
- > 8oz = approx. 237 ml
- > About five 1.5oz shots
- > Usable capacity typically 90-95 percent of nominal
- > Always confirm measured ml before printing retail packaging
Customization and Logo Options
Customization is where most of the margin sits in this category. Our 6oz, 7oz and 8oz matte black stainless steel flasks, and the mini 1-18oz vacuum models, can be ordered with laser engraving, silk-screen printing or debossed logo plates depending on the finish.
Laser engraving is the most durable option on brushed or matte stainless and works well for monograms and corporate gifting. Silk screen suits flat-color logos on coated bodies but wears faster at the edges. For full-color artwork, ask about UV printing and confirm the wear test results.
Packaging customization is usually the larger cost driver than the flask itself. Gift boxes, velvet pouches and printed sleeves each add to unit cost and to tooling. Keep artwork to one or two colors in the first run to hold costs down.
- > Engraving: durable, best for logos and monograms
- > Silk screen: lower cost, less durable on coated surfaces
- > Packaging: often the biggest add-on cost
- > Request a physical sample before approving artwork
Pricing, MOQ and What to Confirm Before Ordering
Our listed wholesale price for the 6oz, 7oz and 8oz stainless steel flask range is USD 1.10 per unit at a minimum order quantity of 50 pieces. The same price and MOQ apply across our mini stainless wine holder flask and the 1-18oz vacuum flask line. These are entry-level figures for standard finishes; engraving, custom color and gift packaging are quoted separately.
At USD 1.10 and MOQ 50, a first order is a low-risk way to test a design before scaling. Be aware that freight, duties and packaging can easily exceed the unit cost on small runs, so calculate landed cost, not just FOB.
Before you confirm, ask your supplier to state the measured capacity in millilitres, the body material grade, cap thread type and leak-test method. We have been supplying barware from Hangzhou since 2013 and quote these in writing on every order.
