Adjusting the O-ring

Having trouble keeping your box airtight? Here is a short guide to adjusting the O-ring.

1. Locate the O-ring

Use a knife or a similar tool to carefully lift the O-ring out of the groove on the inside of the lid.

2. Remove and adjust

Take the O-ring out of the lid, turn it over and put it back in place. Close the lid firmly three times to make sure it's seated correctly. Check whether the seal has improved.

If not, lubricate the O-ring with neutral Vaseline or a similar grease, put it back and repeat the opening and closing routine before trying again.

3. That's it!

If it still isn't sealing better, please check the other steps in our FAQ.
