Best for

• Winter client gifting — A 500ml copper-vacuum flask with a tone-on-tone deboss and a branded coffee pairing lands beautifully in June-August briefs. The flask stays on the desk long after the campaign ends.
• Staff onboarding kits — Pair a 350ml commuter thermos with a notebook and reusable tote. Laser engraving reads as considered rather than promotional, and the capacity suits the morning coffee run.
• Conference speaker and VIP gifts — A 750ml thermos flask with full-wrap sublimation carries a campaign line edge-to-edge. Our project managers handle gift-boxing and split-shipping to hotel concierges for speaker days.
• Field and site teams — For resources, construction and utilities briefs, the 1L vacuum flask with a carry handle and wide-mouth lid survives site conditions and keeps soup hot from breakfast to smoko.

What clients say

"We sent the copper flasks as our winter client gift and three of our accounts reordered the campaign kit for their own teams. The deboss was exactly what we'd hoped for — quiet, considered, the opposite of shouty." — Tamsin, Head of Brand

"The Sense2 team suggested a 350ml commuter size when I'd briefed 500ml, and they were right — our new starters keep them on their desks. Delivery arrived beautifully boxed and a few days ahead of when we needed them." — Asha, People Experience Lead

"Customers consistently rate Sense2 for bringing brand thinking and warmth to every drinkware project — from brief to launch, with delivery that always lands on time." — reputation

Frequently asked

What's the minimum order for custom flasks and thermos bottles? Most flasks start at 50-100 units, with premium copper-vacuum and bamboo-trimmed styles beginning at 100. Larger briefs (500+) drop 20-35% from the 100-qty tier. For pilot runs or sampling ahead of a national rollout, ask our team for a stepped quote across 100, 250 and 500.

How long do branded thermos flasks take to produce and deliver? Standard lead time is 10-15 business days from artwork approval. Many core stainless flask lines brand in 1-4 business days, and 3-5 day express is available on selected SKUs. For Sydney, Melbourne and Brisbane briefs we can sometimes courier same-week on stocked laser-engraved styles.

What branding methods work best on flasks? Laser engraving reads as premium — tone-on-tone, no colour, a clean mark in the stainless steel that never fades. Pad print carries a single-colour logo at lower cost. Full-wrap sublimation and UV print allow edge-to-edge campaign artwork in full colour. Setup is AU$55-$85 per position, once-off.

How long do your thermos flasks keep drinks hot or cold? Our double-wall vacuum flasks hold hot drinks for up to 12 hours and cold for up to 24. Copper-lined interiors extend heat retention further, which is why we recommend them for winter gifting and field teams. Single-wall styles are not suitable for branded hot-drink briefs.

Do you offer eco-friendly or sustainable flask options? Yes. Our flask range includes recycled stainless steel, bamboo-trimmed lids, and plastic-free gift packaging with FSC paper and recycled fill. For briefs with a sustainability story, our creative team will route you to the styles with the cleanest material provenance and longest product-life profile.

Can I see a sample before I order? Yes — free samples ship Australia-wide, dispatched within 48 hours from our Sydney warehouse. Flasks are a hand-and-weight decision, and the right capacity usually becomes obvious the moment someone holds it. Pre-production samples with your actual engraving or print are available on larger runs.
