Terp Wipes are thick single-use cotton pads that are made with 75% ethyl alcohol and 25% distilled water. Each box contains 70 individually packaged swabs. Terp Wipes® are different than the average alcohol wipes because they are thicker and are soaked in ethyl alcohol. Terp Wipes are more absorbent and will not shred like other wipes. Additionally, the ethyl alcohol is grain-based – which is both food safe and non-toxic.
