Baby Boss ME baby bath sponge is made from 100% natural konjac plant fibres. The soft fibres help gently cleanse and massage babys sensitive skin whilst balancing skins pH making the sponge safe also for newborns. The sponge is free from any fragrance, chemicals, colouring and preservatives, and it is biodegradable including the packaging. How to use the sponge Rinse the sponge with water and gently massage your babys skin with it (with or without cleanser). After each use, squeeze out the water and hang the sponge to dry. Replace the sponge after no longer than 2-3 months as the natural plant fibres start to biodegrade over time.
