Cup holder attachable to a stroller, compatible with drinks with a diameter of 5.5cm to 3cm. - Brand: Combi - Product Name: Cup Holder - Model Number: No.13127 - Material: PP - Compatible Size: Diameter 5.5cm - 3cm I received this as a gift, but I already have one, so I am selling it. It seems that it can be used without problems with products other than Combi. It fits many sizes of drinks, from plastic bottles to mugs. I will ship it unopened. #stroller #Combi #cup holder #drink holder
