Returning a Press-On Prism

What is the return policy on  3M prisms?
All prism returns must first be authorized by Fresnel Prism and Lens Co. contact us to receive an RMA number which must be noted on a copy of the invoice for the merchandise being returned.  We are not able to accept returns of Optics that have been cut or removed from the outer carrier nor have your own identifying labels.

3M™ PRESS-ON-PRISMS™  have an expiration date clearly noted on the back of the sleeve – 3 years from the date of manufacture – all prisms sent from FPL are shipped within 3-4 months of manufacture and as such stock rotation and appropriate ordering of the Optics is imperative to prevent “old” stock from being used.  We are not able to accept or replace any expired 3M™ PRESS-ON-PRISMS™.  That being said, the Optics are usable after the expiration date.
