4Pcs Radium Valve Cap for Tire Stem Caps Universal for Car, Bikes, Trucks, Tyre Fluorescent Glow in The Dark Air Cover, Tire Pressure Radium Caps, Modification & Decoration Accessories (Green)

I'm extremely disappointed with the MAPPERZ Tire Valve Stem Caps. Despite the promising description, these caps failed to deliver on several fronts. Issues: 1. Poor build quality: The plastic feels cheap and flimsy, and the threads are uneven, making it difficult to screw them on. 2. Glow-in-the-dark feature doesn't last: The fluorescent glow fades away within a few hours, rendering it useless. 3. Color inconsistency: The green color is more like a dull yellowish-green, not the vibrant green shown in the product images. Conclusion: For the price, I expected better quality and performance. Unfortunately, these tire valve stem caps are a waste of money. Unless the manufacturer addresses these issues, I wouldn't recommend them to anyone.

Purchased these tyre valve caps purely & solely for the purpose of covering the tyre valves of the tyres on my car. The originals were lost when the attender filling air a couple of months back conveniently forgot to put them back. I decided against getting anything metal, as eventually they can get rusted (depending on the metal), and then rectifying that issue in a time of need would be an unnecessary bother. Was highly skeptical when purchasing these valves as I was not sure of the composition material and in the specifications of the product the seller had mentioned the full scientific name. After receiving the pink tyre valve caps, they seem like to be made of sturdy plastic. However, I do not think this radiates in any manner in the dark. Have been using this for three days and have not seen a light like effect in the night. I had purchased this because (a) I had a very basic and specific purpose (b) it came in a quantity of four pieces & (c) it was only ₹ 90/-. Looked at other much less flashy / bright alternatives, but their minimum order quantities were not ideal. These caps close all the way down to the valve so be careful to not over tighten it.
