The Universal Lens Cap does have a warranty. In fact, a lifetime warranty! For as long as you own the product, you are 100% insured against defects in material and workmanship.
However, we do NOT provide a warranty against damage or any other defects/issues caused to your lenses WHILE using or NOT using the Universal Lens Cap. In addition, we will not replace lost or stolen Universal Lens Caps.
If your lens breaks while using our product, we are not liable for your camera gear, its repair/replacement, nor act as a financial insurance agency against potentially harmful issues to your camera equipment, especially your lenses. The Universal Lens Cap acts as an aversion tool to mother nature and potentially harmful elements. That is it. We strongly advise you seek out and invest in insurance for your gear just as any other professional would do in any other industry! :)
