We've been testing these cups for six months now. And, after daily use and testing we felt that it was time to make them available to the world!
Here's some questions and answers that we've put together for you. If you think we've overlooked something, or you need more info, have feedback>> please email us hello@rubbercuppy.com.au


What makes Rubber Cuppy the better choice?

- Zero grams of plastic

- Made from used bicycle tubes that would otherwise go into landfill

- Supporting, and working with local bike stores to close their loop and become circular

- Glassware, we don't use any chemicals or toxic compounds in the making of our cups

- Vacuum sealed lids means no leaks

- Your coffee order can be written on the rubber, we recommend chalk markers or paint pens. Sometimes, the reusable cup is great- but then comes the sticky notes... Rubber Cuppy let's you avoid that.

What is Rubber Cuppy made of?

Rubber Cuppys are made from sustainable food safe glassware- glass is one of the things that can truly be called environmentally friendly, and fully sustainable. And you can read more here. The lids are made from metal. The glass is flint glass, that can be used in high temperature. Did you know tempered glass can't be recycled? Our glass is fully recyclable. And the rubber sleeve is made of up-cycled bicycle inner tubes, that have been ridden on the streets of Melbourne- before finding their new home on your Rubber Cuppy.

Oh, and- there is zero grams plastic on your Rubber Cuppy. Which we think is pretty neat.

Does Rubber Cuppy leak?

Our lids have a built in vacuum seal that activates when the lid is closed with your warm drink inside. It requires only a gentle turn of the lid to get it into place. If you overturn, you run the risk of damaging the threading. If this happens, please write to us for a spare lid (check our online store).

If your cup is leaking, in most cases it means there was some liquid already in the lid that has run out the side. Check the lid is dry before putting on your Cuppy to ensure zero leaks. Otherwise, you may have dinged the lid or broken the threading. Check our online store to order a replacement lid. 

Can I pick up my coffee straight away?

You can pick up your fresh hot coffee straight away, no problems. For a cup of tea, or boiling water it may need a minute. And soon you will be able to order an additional rubber grip. The rubber helps to keep your coffee insulated on the inside, warm on the outside, and the texture gives you extra grip.

Australia / Tradies / Dashboards - YES.

Up-cycled bike tubes. But why?

Adam here. Tubes are every bike stores big throw away item. If a punctured tube is beyond repair, it's going straight into landfill. By turning these into new meaningful products, we give it a new lifecycle and start to reduce its carbon footprint. We're also celebrating the bike stores that get involved. You can see who they are on Our Stockist page.

Care Instruction for Rubber Cuppy

Handmade = hand wash. Your friendly barista may even give the glass a rinse for you, and the rubber can be wiped with a damp cloth. We don't recommend putting these in the dishwasher or removing the rubber sleeve. They just need a quick rinse under hot water and a wipe.

Can I get my company branding on a Rubber Cuppy?

We now offer two types of branding. Engraving, and print logo branding. There are minimum orders, please contact us to find out more, accounts@rubbercuppy.com.au

Where are Rubber Cuppys made?

Rubber Cuppys are handmade in Melbourne, using locally collected bicycle tubes and imported Italian glassware. Any printing is done with our local Eco printers using plant-based inks and recycled/or up-cycled paper.

Can I order a spare lid for my Cuppy?
