Piešťany-based G&R spol. s.r.o. will sell its filters under the brand name '84.5mm camera filters', taking the name from the typical width of a Type P filter. Initially, G&R plans to offer a selection of 23 filters in two sizes: 84.5mm x 100mm, and 84.5mm x 150mm. The rectangular filters are compatible with Type P filter holders from the likes of the recently-resurrected Cokin, and much like that company's products are made from a plastic polymer known as CR-39 or allyl diglycol carbonate. CR-39 is commonly used in eyeglasses, and has the combination of good optical properties, and higher scratch resistance than other uncoated plastics. It's also harder to shatter than optical glass, and has good resistance to heat and common solvents / chemicals.

G&R's filters at launch will all be single graduated types, with a choice of five graduated neutral density filters, and 19 color graduated filters: purple, pink, blue, orange, green, yellow, tobacco, denim, and antique. These should be followed by four striped filters that are graduated on both sides of the stripe: blue, purple, pink, and orange. The company further notes that it is planning to offer filters intended for cinematography in the future.
