• This is a lid seal for OmieBox UP. 
• It must be assembled on the bottom tray to make OmieBox UP leakproof. 
• After each use, please remove the lid seal and clean with warm, soapy water. Please let dry completely before re-installing again.

 *IMPORTANT*

• This lid seal will only work with OmieBox UP. All spare part purchases are non-refundable. The best way to see which OmieBox you have is by checking the box shape.
  
• If your box is rectangular, it's an OmieBox UP and this is the correct part. 
• If your box is square, then it's an OmieBox and this will not fit.
