return policy?

[http://dummy.us.eu.org/robert (robert)]

I haven't yet bought anything from InkPalette, but I am considering doing
so.

I am planning to buy 4 Sheaffer New Piston converters, but if they don't
work out, I'd like to return them (or, at least, the ones I don't
open/unpackage).

What is your return policy?

Thanks.
