I represent a Moroccan company specializing in school supplies, and we're in need of school backpacks for kids, both with and without wheels, for the upcoming school season. We're looking for options suitable for ages 6-7, 8-9, and 10-11. Could you send over some product photos/videos, along with details on sizes, materials, MOQ, and unit pricing? Also, please include info on delivery and production lead times. We're considering a total order of up to 50,000 units across models. Thanks!
