Not if something was defective but if you think something could be changed or would like to see other options?
My daughter got a Melissa and Doug Riding Club puffy sticker set for her birthday. She opened it and started playing with it and asked, "Where are all the boys?" I started looking through all of the other sticker books they have and they're all pretty gender-specific.
I emailed the company and asked if they have any supplementary boy riding club sticker sets that we could purchase. Spoiler: I don't think they do. I see a pirate set (all boys) but no other horse related sets.
