Good news, Keenz actually has their own official accessories, so you don't have to hunt for third-party options! Someone in my mum group mentioned that the Keenz Air Plus has a dedicated Snack Tray attachment, though it's model-specific, so worth double-checking which Keenz wagon you have before ordering. They also have an organiser bag that clips onto the handlebar with sliding buckles, which is handy for snacks and bottles on the go. The trade-off is that the official accessories can be a bit pricier, but the fit is reliable since it's designed for the stroller, versus universal holders which may or may not clamp on securely depending on the bar shape.
