This is holder for ABC Design stroller, specifically for Salasa4air model, however I suppose it should work with any type of ABC design stroller type. It attaches on connector for bag. Big advantage if this is design is its small form factor. It will not take a lot of space in you storage.

All 0.3 and 0.5 l cups should fit. You can use adapter that can help you hold smaller diameter cups and bottles.

Added dimensions photo to check if it will fit.
