Walker Signature Tape Our Signature Tape is the thinnest 4+ week tape on the market! It’s only 6.5 mils thick. Most 4+ week hold tapes are around 10-11 mils thick. We started with our Ultra Hold Tape and made it thinner and stronger. The combination of the dull finish, flexible liner, and incredibly thin construction makes this tape incredibly comfortable to wear and gives a lifelike appearance. Because it’s so thin, it also leaves behind less residue than any other 4+ week tape, making it far easier to clean after removal. The tape is clear with a white liner. It is ideal for lace units. Hold Maximum Wear (2-4+ weeks) tapes are the longest-lasting tapes we make. Depending on temperature, humidity, and body oils, they can last up to six weeks. Because they’re usually the most tacky, they require more skill to apply. You can expect a 4+ week hold from this tape.
