Millstream has become quite well know for the high-density, closed cell foam that we use as liners in our boxes. Because ripple foam is molded rather than cut, it has a velvety, elastic surface that wears better and longer than more rigid foam.
Our ripple foam is available as replacement foam liners for boxes such as ours. All foam items are able to be trimmed to the size you need with household scissors and have an adhesive backing with a peel-off liner.
Refills come in three sizes: small (4.125"x 2.75"), medium (5.5"x 3.625") and large (8"x 4"). Each package contains one sheet of ripple foam and one sheet of flat foam. Flat refills contain two sheets of 3/16" flat foam.
A Millstream Boat Patch is a 12"x15" sheet of foam with an adhesive backing designed to be mounted wherever you need to pin a fly - boat, truck, fly tying bench... anywhere. Available in ripple foam (shown here) or 1/8" flat foam.
