Many shoppers will agree that walking into a store where they can see, touch and compare unfamiliar products is preferable to ordering them from a catalog or website and hoping for the best.

This can be especially true for green products, some of which are produced with methods and materials that are unlike what's found in mainstream items. Products made with recycled goods like denim jeans, candy wrappers, rubber tires and boat sails are a growing niche. The wave of interest in alternative products for construction, as well as household use has creating a new retail concept: "green" stores. Here's a sampling.

GREENTIQUE: 116 East Main St., Port Jefferson, 631-509-1815

After a year in Huntington, Jennifer Fondacaro relocated her store to Port Jefferson. Jessica Kearns, 24, of Stony Brook, says she especially loves the recycled jewelry, particularly the bottlecap bracelets (about $20), which she buys for herself and friends. "I think it's a shame to waste so much and it's fun to see what can be done with throwaway stuff," she says.

When Robert Meinke's concept store opened in 2009, its recycled and bamboo-wood shelving were stocked with a hard-to-find variety of eco-friendly products. "There's always something new," says Michail Levy, a Freeport contractor who buys water filters, paint and home items such as bamboo shower curtains that stand up to mold and mildew. "These things are long-lasting," says Levy. "So I save money while I'm helping the environment."

Ten-inch diameter models cost $699, including installation. You'll also find solar, motion-activated landscape lighting ($89.95) and Eco-Kits that teach kids about renewable energy ($10.95).
