Product Size: Tapered Cork Assortment Set contains 12 pieces of 2inch/ 52.5mm in top diameter, 48mm/ 1.89inch bottom diameter, 17mm thick tapered cork. Material: made of high density natural cork, non-patterned, which will not bend or shatter during long-term use. Easy to Use: the cork is flexible and soft, but will not break easily when pulled out, and the tapered design fits perfectly into the mouth of the bottle. Highly Airtight: the conical design of the cork fits the bottle mouth well and maintains a good airtightness inside the bottle, without altering the taste of the drink and facilitating its fermentation. Versatile: our tapered corks are perfect for home brewing, parties, restaurants, weddings, holiday celebrations or kitchen needs, and make sweet gifts for friends and family.
