These are packs of 4 felt Hoover Discs (colours may vary) 
Pop 1 disc into your hoover (see video) and change when your hoover needs emptying :) 😜👌
These little felt Discs are soaked in fragrance oils and dried so your hoover can smell lovely and not of dirt & dust. 
--------------------------------------
**WASH HANDS AFTER TOUCHING THE DISCS AS THERE MAY BE OIL RESIDUE TRANSFERED TO SKIN, DO NOT PUT YOUR HANDS NEAR YOUR EYES OR MOUTH AFTER HANDLING DISCS!! **
