This is a multi-functional pass case for pilots. I bought it, but I no longer use it because I changed my mode of transportation. Made of durable material, I think it's safe for elementary school students to use. If you are looking for something for school entrance or kindergarten preparation, how about this? The price includes the product cost and shipping. I will ship it anonymously.
