Style.Lab by Fashion Angels: Harlow Color-Block Backpack & Pouch Set - Navy & Pink - Kids Travel & School Bookbag, Stylish Retro Design, Girls-Boys

I found my Style Lab pouch at Ross for $5 but you can get this or similar elsewhere (here's Walmart link for the pouch + backpack for $20)... They are super colorful and spark joy, but there are similar/less loud pouches on Amazon if you just search for "style lab pouch"... Hope that's something that can work for you. https://www.walmart.com/ip/Style-Lab-by-Fashion-Angels-Harlow-Color-Block-Backpack-Pouch-Set-Navy-Pink-Kids-Travel-School-Bookbag-Stylish-Retro-Design-Girls-Boys/15163307031?sid=d3d2d2df-1d45-4cd0-8767-6c2e24eff918 There's also this corduroy one that's fairly large and rectangular: https://a.co/d/03S7AXsU The there are smaller square ones but are still a decent size. This one isn't available anymore but Amazon is always good about suggestions!: https://a.co/d/0eBL0RbO
