Umbrella Holder for Bicycle, Riding Umbrella Stand, Rain Umbrella Fixer for Strollers, Foldable Telescopic Umbrella Stand for Rainy Days, Sunshade, UV Protection, Compatible with Electric Bicycles and Strollers, Black, Tri-fold Thank you for viewing. This is a product I purchased on Amazon. I tried attaching it to my bicycle once, but I never actually used it, so I am selling it. I attached it once and immediately removed it, so it has never been exposed to rain. I have opened the package, so I have listed it as "Like New." Please understand that this item has been stored at home and is a used item. Thank you for your consideration.
