Bellanca Air Canada And WestJet Personal Item Size Backpack Under Seat Carry-on Bag Flair Airlines Hand Luggage (Black, 16x12x4/6In)

Thank you.I found the old product from Amazon. https://www.amazon.co.uk/CabinFly-Bellanca-Expandableto-Lufthansa-International/dp/B0DNWDZCB9/ref=cm_cr_arp_d_product_top?ie=UTF8 Many people like it. Some say it broke down after some use. I'm ok with the price tag. I looked into cheap bags from Temu but I didn't like them. They seemed too static in design and square like. I'm finding it difficult to find a 40x30 bag, most that are on sale are 40x25. The reason I want 15cm version is that a lot of Helsinki - Stockholm flights are operated by Finnair with that policy.
