Henna Sealant Tape (Mefix Tape) Size: 2 inch x 10 yard Why Sealant Tape? Henna dries, shrinks, cracks, and pops off. This is bad. We want it to stay stuck on the skin for 4-12 hours. Very tricky. Wrapping up with Sealant tape will hold the paste perfectly in place. Clothing can be put back on, and you don't have to be careful since the design is wrapped and protected. Super handy for nighttime. The tape must be cut into strips. It's flexible, breathable, soft, and comfy. The nearly perfect aftercare solution for special designs and sleeping. This is the tape preferred by all artists! Not every situation works with citrus sealant.
