The iconic [MSK] was listed as TIME's 100 Best Inventions of 2020. Now updated to include improved velcro adjustment and a removable frame for improved breathability.

A set-up guide is available here.

The [MSK] is a non-medical, reusable face covering designed for Adults and LittleHumans. Available in two sizes, LARGE and MEDIUM, to enable you to choose the best fit for your face shape.

The LARGE size fits adult faces with more pronounced facial features, whilst the MEDIUM is suited to petite facial features (including smaller noses), and LittleHumans. If you find that you’re between sizes, you’re lucky enough to be able to choose either size. Both sizes have multiple adjustment settings.

The [MSK] follows the contours of the face and is supported at the neck for optimal comfort. It can also be worn as a collar for frequent removal throughout the day.

*Neither changes nor returns are accepted for hygiene reasons.

Adults who are between sizes can choose either MEDIUM or LARGE.

About PM2.5 Filter

  • _2 filters & nose wires are included with each purchase
  • _Use: Insert PM2.5 filter into the (MSK) with numbers in order, exposed to the inside face of the mask and numbers in reverse, to the outside face of the mask.
  • _Layer Filtration technology: Filters are made of activated carbon and non-woven melt-blown filter cloth and a five-layer filter system which works to absorb a range of airborne contaminants.
  • _Size: The filter size is approximately 12 x 8 cm, which is suitable for most adult faces.
  • _Safety: We recommend replacing PM2.5 filters after a week of use for the best performance. Disposable supplies can't be reused or washed. The mask without the filter is a 2-ply tightly woven construction.

Arabella is our hero!

I bought this on behalf of my 77 year old neighbour Doreen who has been looking for a mask that wouldn’t effect her hearing aids. It all looked and sounded good! The mask arrived but Doreen was struggling to put it together and get the right fit. She was disheartened... Then Arabella from the company called her and spent a considerable amount of time and patience explaining how it worked and how to get it to fit. Doreen just called me to say how happy she is now it fits! Arabella.. you are my hero for today. Thank you so much and all the team for making one very special lady Doreen a very happy lady. God bless you all. 🙏🏼

Great Mask

Would be better if more of the nose wire was included, mine is currently towards the end of its life already.

Thanks for the feedback on the Batch 1 BETA unit C H, happy you like the (MSK)! We sent over some spare nose wires for you and as a result of your feedback, we have machined thicker metal nose wires and added a spare for BATCH 2, 3 and onwards!

Fantastic design

I love this mask! Fashionable and comfortable! Who knows how long we will all be required to wear a mask around the place - worth getting one you're happy with! I'd highly recommend this one

Over the moon 🌓

The Petit Pli facemask is one of my favourite purchases of 2020. For my job, dressing professionally is as important as behaving professionally in front of clients and in the office. However, I have quite a small face and need to wear glasses. Finding a mask which doesn’t cause my glasses to fog, fits my face and is chic, is a miracle. I highly recommend the Beta(MSK) to any young professional!


I got two of these masks as part of the beta release - the blue and the green. Apart from the texture and the colour, I love that I can wear it around my neck. So, unlike the mask I had with me already, I don’t have to entirely take it off when I need to. Besides, it also feels like a fashion accessory because of its unique design. It has two velcros - and the material of the velcro is different - so it doesn’t stretch the fabric like how traditional velcros usually do. Since there are two, I’m also able to adjust how tight or loose I want my mask to be. I’ve been using this as my go-to mask for a couple of weeks now since I got it, and I’ve got a lot of compliments for it, and I feel like many people I know are going to be getting them 😍
