Surprisingly smooth  and sturdy!
I usually use a bamboo toothbrush, but they aren't as smooth as plastic. However these are extremely smooth! I'm very impressed at the durability of it too. It feels very sturdy and the bristles work well. The child sized brushes are cute an appropriate. The packaging is all cardboard except 2 small stickers to seal the large outside box. Each brush is also individually packaged in a cardboard box. Over all very please, and I will purchase these again.
