New beach accessory makes waves

Make this summer a memorable one for your little mermaid by surprising her with a Mahina MerFin from Australia. This fintastic beach and pool accessory is a rubber monofin — molded, in part, from recycled materials — that she will put both feet into and instantly transform from a biped into a mythical sea creature. (When she’s ready to step ashore, your little mermaid will tug on the single flick release strap at the ankles.) The rubber flippers come in three lovely marbled colors; choose from aqua marine, coral pink, or sunset orange. Judy Ishayik of Mary Arnold Toys on Manhattan’s Upper East Side says that she has already re-stocked the fins twice this season — not surprising as her customers report attracting scores of admirers poolside. The MerFins come in children’s sizes 12-2, 2-4, 4-6, 6-8, 8.5-10.5, and 10.5-12.5, and if mom wants to make waves on the beach, too, Ishayik can place a special order for adult-size MerFins.
