Baby Boss ME toothbrush is a sustainable alternative to regular non-recyclable plastic toothbrushes. The biodegradable handle is made of BPA free, organic and sustainably-grown bamboo, and for the bristles we have used extra soft BPA free nylon to ensure a gentle and effective solution for oral health of your baby boss. Care: Keep the brush in an open-air toothbrush holder or any other dry area. Replace the toothbrush after 2-3 months.
