These bamboo nappy liners are a clever design that will catch the solids but let the wetness soak through into the nappy meaning less icky work for you. They are to be placed on top of the nappy next to baby's bottom. Use disposable liners when out and about for convenience but when you're at home please use the washable fleecy liners supplied with Littlelamb nappies. After use please bag and bin. Please do not flush these down the toilet they may  contribute to the fatburg issue if you live in an area with old Victorian sewers. 100 liners per roll. Made from 100% Bamboo PLA.  The huge benefit of PLA as a bamboo-derived bioplastic is that it naturally degrades when exposed to the environment. PLA liners will take between two and twelve months to degrade fully in a landfill situation. It's the same stuff most tea bags are made from!
