We recommend you remove and rinse your lid with clean water as soon as convenient once you’ve finished your beve.

If your concoction was particularly thick we also recommend removing the seal and allowing the water to ‘flush’ any residue from the groove.

If you find yourself with one foot out the door with no time to wash the lid properly, at least pop it off of your jar.

Mild dish washing detergent may be used if a good clean is needed, but be aware that this reduces the durability of the surface coating applied in the factory, and you may need re-oiled the lid sooner.


We recommend you use a food safe kitchen timber oil – these can be found at hardware or craft stores, and are usually marketed as being for wooden utensils, chopping boards, or even bench tops.  Be sure to read the manufacturers instructions to ensure you allow enough time for the resins in the oil to cure.

If you prefer a less ‘hardware’ option, you can use olive or coconut oils.  These will reduce the propensity for the pores in the bamboo to adsorb water, but they don’t ‘harden’ in the same way and will need to be reapplied more frequently.

For the love of bamboo please don’t leave your Bamboo Tumbler Lid on a jar once you’ve finished your beverage!!!  The lid will go moldy very quickly if you do.

Clean dry lids may be stored on a clean dry jar, but in the wild lids can also be found happily residing in kitchen and desk draws and shelves.


Bamboo Tumbler Lids can be air or cloth dried.  If air drying, do so with  in with as much of the surface areas exposed to air as possible.

Please allow us to use some theatrical creativity in answering this question.

us:  NO!!!

you: But I really want to put my tumbler in the dishwasher!

us: NO!!!

you: (to the audience in a muttered voice) as soon as they leave I’m going to put it in the dishwasher *wink*

us: I heard that, and now I’m not leaving until you’ve washed that lid properly!

you: hmmph *throws hands onto hips*

audience: ooooh

us:  *cross arms, taps foot*

narrator:  Oh little bear, don’t you know that Bamboo Tumblers are a natural wooden product?  Dishwashers are nasty artificial monsters where high pressure jets of water, high temperatures, corrosive substances and steam freely roam looking for organic particles to devour and then redeposit on our beautiful coral reefs.  Your little Bamboo Tumbler Lid will be devoured in an instant** in such an environment

**in reality you might get away with it once or twice, but prolonged dishwasher exposure will mercilessly strip the protective and natural oils from the product, rendering it defenseless against the onset of mold and other nasties.  The pressures and steam may also cause delamination of the bamboo cores.

you:  aww but…

us:  ahem

you:  fine…

Mold can occur due to a few different reasons:

  1. you had a smoothie, left the lid on the jar, then went to the gym.
  2. you had an OJ, left the lid on the jar, then went on a netflix bender.
  3. against all better judgement you left the lid on the jar.

If you find yourself with a golden moldy, depending on the extent of the mold you can try using vinegar to kill the mold and clean thoroughly with a sponge or cloth.  In the most severe cases, sanding and re-oiling the lid is the only way to bring it back to life – be sure to wear a dust mask so you don’t breathe in the nasty spores.


Years ago, four robots in stasis, awoke to find themselves in the strangest of places… the rest, as that say, is history.

Alternatively, if you don’t believe in space moon rock alien robots, you might prefer to believe that your Bamboo Tumbler Lid is the result of necessity, a ‘simple’ vision, and a touch of some sort of hyperactive disorder. When beloved wife thought of the concept of a wooden tumbler lid, she sought the assistance of big industry to make it happen.

Unfortunately, ambitious wives are an unfamiliar concept in big industry, and with a baby bump she wasn’t taken very seriously. Enter endearing husband, who crafted the first wooden tumbler lid using an assortment of small parts from the hardware store.

For a time our bamboo tumblers were made by the same technique as the very first prototype (under our old name Poppy’s on Penshurst). In recent years, the popularity of our tumblers necessitated that we become more inventive – and we did so by building our own manufacturing equipment, which now sometimes works more than it doesn’t.

What’s hasn’t changed since the Poppy’s on Penshurst days, is that when the very lid in your hand was conceived, husband (Tim) was most likely piloting the machine in 35+deg C tropical conditions, whilst wife (Penny) was probably operating the laser, whilst responding to online queries, whilst entertaining a two year old, cleaning up after a puppy, and more than likely looking forward to an end-of-the-day smoothie from a new prototype tumbler lid that no one else in the world has seen yet.
We hope you enjoy using your tumbler as much as we have enjoyed the journey of creating it.



Our Bamboo Tumblers are made in our Townsville Tumbler Facility (aka a dirty great big shed) in the Bohle Industrial Estate. We’re big believers in the makers movement and open source technology, and nearly our entire production line is a labour of open source love (aka hours spent tinkering when we probably should be sleeping).

The bamboo your tumbler is made from started life with smooth ambitions to become a benchtop in icy cold Melbourne. For better (or worse) we coaxed it to sunny North Queensland, where after a few hours of noise, sawdust, and very occasionally flames, the sheet emerges with looking like a giant sheet of bamboo bubble wrap.

The basic tumbler profile is then further processed to cut any face profiles (eg our new Dished Tumblers), and then hand slotted, sanded, laser etched and oiled.

Finally, every tumbler lid is buffed squeaky clean, assembled and boxed ready for shipping to it’s new home.


Bamboo Tumblers are reusable and help to reduce your waste. get your next take-a-way juice or smoothie in it and you’ve already helped the planet.

They are made with little emissions and only a small amount of waste is produced.

Bamboo is a Sustainable natural product and is harvested with minimal impact to the Forrest floor.

Stainless Steel Straws have so many uses and can be used again and again, just like cutlery.

Not us.  His name’s Phil, although much like The Stig we can’t show you his face.

But seeing as you’ve come this far anyways, please join us in raising your tumblers and tipping your lids in appreciation of the awesome work he’s done for us (and respect for his injuries arising from deep coding misadventures).


Sendle recommend waiting a few more days then to contact them in the event it till hasn’t arrived.

Sorry this happened! you can contact the company it was shipped with and apply for them to reimburse you, or you can purchase another Jar and just pay the shipping.


We try to use Sendle where possible. However some destinations are unavailable and we then rely on Australia Post. If you provide us with a PO BOX Australia Post will be used.
