I ship this filter in a 6X6 box only because envelopes get lost more easily when shipping international.  The following listing is for 1 Ilford Multi-grade 500H GREEN contrast filter.

The glass is Dichroic nano coated glass. Please message me any questions you may have about my products. 

Free shipping is only to the lower 48 US States. Ships world wideThanks! Sincerely, Jay Overmoen,
