GUARANTEED SAFE & SECURE CHECKOUT

The ultimate confidence booster! Designed for women who want to make a statement, these ultra-padded inserts deliver an instant lift, giving you that dreamy wow factor in seconds!

Why You'll Love Them:

  • Instantly increases your bust by up to 2 cup sizes for a fuller, more dramatic look

  • Perfectly tailored for low V-cut tops, creating a natural, feminine silhouette

  • Double-sided for extra security

  • Water and sweat-resistant to keep you looking fabulous even in hot weather

  • Prevents nipple slips in low-cut tops

  • Stays put and keeps clothing in place

  • Interchangeable between outfits, no sewing required

  • Not suitable for individuals with sensitive or thin skin or for women who are pregnant or breastfeeding

Unlike a sticky bra that is supported by adhesive, Grailz inserts are supported by the clothing and cannot stay up by themselves. It's important to wear them in tight, structured, and fitted tops.

Before using Grailz inserts, make sure your breasts are clean and dry. Avoid makeup, oil, lotion, or other body products, as these can affect the adhesive's effectiveness. First, put on your clothing, then place the inserts onto the garment. Finally, scoop your breasts and stick them onto the inserts to secure them in place.

Carefully peel off the insert, starting from the top edge, and slowly remove it from your breast. Repeat this process for the other side. For optimal preservation, store BARE inserts in their protective films immediately after use.

To clean the inserts:

1. Hand wash only; do not machine wash or dry.

2. Use your fingertips to gently clean the adhesive, avoiding fingernails.

3. Rinse with warm water to remove residue.

4. Carefully shake off excess water and lightly press to squeeze out remaining water.

5. Air dry in a dust-free area.

6. Once dry, reapply protective films to prevent dust and lint.

After cleaning and the inserts are dry, reapply the protective film to the inserts and store them in their original packaging (satin sachet). Keep them in a cool, dark place away from dust and debris.

"Wore these for a big event; forgot I even had them on! They stayed secure, no weird lines, and so easy to clean."

My New Go-To Inserts

Harper | 31-01-2025

"Ok. Listen up right now. I’ve tried them all and these are THE BEST. These ones are the real real deal like do not move. They stay on through sweat, water, all the above. They don’t stick out on the sides or top at all and make your boobs look so naturally big not like fake big. You cannot tell you’re wearing them at all. I’ve been searching for soooo long for ones to wear in swimsuits and I’m so freaking happy I found them. Save the damn boob job, get these. I’ll wear these things till I die"

Kept my tits together, lol

Evelyn | 10-09-2024

"I went to an edm concert with hard dubstep music. I was head banging and jumping up and down so hard I think my brain dislodged in my head. I was soaking head to toe. But my Grailz inserts faithfully stayed with my tits all night and were still sticky when I came home. I would 100% recommend and buy again"

Best Sticky Bra

Zoey | 09-04-2025

"This is the best sticky bra i've ever owned, and I've tried several different kinds. It stays in place all night and gives me great lift without adding a huge amount of padding. I've worn them with so many different tops. So glad I found these!"
