Yes there is a 30 day money back guarantee. If you don't like them send them back for full refund.
I offer the following grades.
- Rosco 3-stop (ND8) filters, 31mm diameter with tab
- Rosco 2-stop (ND4) filters, 31mm diameter with tab
- Rosco 1-stop (ND2) filters, 31mm diameter with tab
If you want an ND16 then you can get that by stacking one 3-stop filter and a 1-stop filter, shown on left below. For ND32 stack a 2 and a 3. If Roscoe offered darker film I would be happy to sell them but they don't.
Absolutely you can get a sample swatch pack of filters from Roscoe but you would also have to pay for shipping and cut them down and you would still need multiple filters to get a to an ND16 or ND32 and figure out how to attach them to the camera or cut them to fit inside the removable glass filter (P3 Advanced and Professional only). You would also probably need to buy two swatch packs to get enough filters. Also the swatch packs I've gotten before as samples had some scratches on them. Good for determining what filter you wanted but not recommended to put on your P3.
Below is an example of SOME of the filters I rejected because of quality in just the last few months. I stopped buying from the authorized Roscoe dealer in Chicago because I had gotten 3 bad batches of filters. I also lost 3 shipments due to UPS. I now order in large rolls and throw out the first few layers due to damage.
If you are not happy with them for ANY reason you can send them back for a full refund. If you want to try to save a few bucks by ordering the sample swatch books then go ahead, you might get a great pack and it might work out fine.
Thanks again for the feedback.
cheers
