+ I can't open my lunchbox anymore. What can I do?

By using sealing rings your box is leak proof. However, when eating very hot food, negative pressure can form which makes it much more difficult to open the box. Please let the food cool down before closing your box. For very hot food (over 70 degrees) it is advisable to remove the sealing rings – but be aware that now the box is no longer leak-proof. 

Tips for opening:

• Tiffin Swing+/ Tiffin Double+/ Tiffin Pro+: we have created a video to help you.
• Shanti Box+/Tiffin Bowl+: to release the negative pressure and to remove the separator plate, please pull the tab on the sealing ring a little.
