From the instruction manual parts list: - Wheels x 2, Washers (Large) x 2 installed - Dapping screws + Washers (Small) 1 set, no spare (3 sets are used, so there is no problem) - 10 Allen wrenches included instead of 2 There are no missing parts for use. I have disposed of the outer box, so I will wrap it in bubble wrap and attach the shipping label on top. Please refrain from price negotiations as shipping and handling fees are included.

The following is the product description: Brand: Rozally Color: Black Material: Polypropylene (PP) Recommended Maximum Weight: 25 kilograms Item Weight: 1.7 kilograms Product Dimensions: 55 length x 33 width x 36 height cm [Supervised by a Nursery Teacher] Rozally Baby Stroller Step is finally officially released. It's a buggy board-type connecting step created from the voices of parents who have a conflict when the older child wants to ride in the stroller when the younger child is born and they go out with the stroller. It is a model where the older child can sit together because it is a step board with a saddle. In planning and design, we received advice from a [nursery teacher] and produced the product with an easy-to-understand instruction manual. [Compatible with all strollers] Although there are cases where it is sold as a genuine option board as a two-person ride attachment adapter from each manufacturer, the auxiliary pedal may not be sturdy, or the saddle may not be attached, resulting in a varied finish. Rozally Baby Stroller Step is compatible with all models, and we have focused on the functionality of the baby stroller step with particular attention to detail.
