The bottom mold clips under the free edge in place of a paper form, and the top mold shapes the surface, so the extension is finished when you remove the molds: no filing, no extra sealing layer and no gel on the underside. The trailing edge is about 0.2 mm thin to sit flush with the natural nail, and the wing design makes French extensions easier. The forms are made of PP: wipe them clean after use and reuse them.\u003c\/p\u003e\n\u003cp\u003eUse with milk, jelly or crystal-clear extension gel.\u003c\/p\u003e\n\u003ch3\u003eHow to Use\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003ePrep the nail.

For a thicker extension, use a smaller bottom mold or leave a little space between the top and bottom molds before pressing. If no bottom mold fits, trim it to shape.\u003c\/p\u003e\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: MR NAIL\u003c\/li\u003e\n\u003cli\u003eStyle: Sandwich dual forms (top + bottom molds)\u003c\/li\u003e\n\u003cli\u003eShapes: W557 Oval and W558 Short Oval\u003c\/li\u003e\n\u003cli\u003eContents: one top and one bottom mold per size, sizes 0–14, for each shape\u003c\/li\u003e\n\u003cli\u003eMaterial: PP, reusable\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MR NAIL","offers":[{"title":"Default Title","offer_id":68022604562543,"sku":"MRN-W557-W558-TRIAL","price":9.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/5007\/9087\/files\/mr-nail-w557-w558-sandwich-dual-form-trial-pack.webp?v=1793068071","url":"https:\/\/gelpolishco.com\/products\/mr-nail-w557-w558-sandwich-dual-form-trial-pack","provider":"Gel Polish Co.","version":"1.0","type":"link"}
