PLANTOYS alphabet blocks. Pictures are drawn on the back of the alphabet blocks, so I think they are good for studying the alphabet. I bought them because they are very cute and good for studying, but I am selling them because I don't play with them much. I don't see any dirt or scratches on the blocks, but I apologize if I missed anything. The box is dirty. * When shipping, I will take the blocks out of the box and fold the box to include it. Thank you for your understanding. Sustainable Play PlanToys(R) values the limited resources on Earth and contributes to the realization of a "sustainable" society that does not burden the environment. It is a wish that children will be able to get as close to nature as possible. Children who have cultivated a heart that values nature will surely protect the Earth in the future. PlanToys(R) has been disseminating this philosophy around the world and has conveyed the importance of nature through wooden toys.
