Child's bicycle helmet, suitable for head sizes 49-54cm. It's the OGK PAL model. The second photo shows a dent. My child found it too small, so it was only used about 5 times. The black part is made of a material similar to styrofoam, so there are small dents like the ones in the third photo. - Brand: OGK - Model: PAL - Size: 49-54cm - Intended Use: Bicycle helmet Please refrain from price negotiations. Thank you.
