PRODUCT DESCRIPTION

PATENT PROTECTED

The most padded insert on the market. The go-to for that wow factor. Instantly boost up to 2 cup sizes. Recommended for tops with structure in the chest area.

Triangular-shaped, best for low v-cut tops
Boosts up to 2 cup sizes
Double-sided adhesive for extra security
Sweat and water-resistant
No sewing required and interchangeable between outfits
Our inserts are not intended for individuals who have sensitive or thin skin, or women who are pregnant or breastfeeding

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

For the perfect fit, we recommend choosing your true size. Only size down if you are in between sizes.

Have augmented breasts? Please check our FAQ section to see if they are suitable for you.

HOW TO USE BOOMBA INSERTS

Please note that our inserts are not intended for individuals who have sensitive or thin skin or women who are pregnant or breastfeeding.


Like traditional inserts, BOOMBA inserts need to be used inside clothing. They cannot be used by themselves.

  • STEP 1

  • Wear the garment on your body. Tighten the garment if possible for best results.

  • STEP 2

  • Stick the inserts onto the inside of your clothing item and not to your skin.

  • STEP 3

  • Scoop breasts up and towards the centre to create cleavage.

  • STEP 4

  • While scooping, press the insert onto the breasts and press firmly to secure.

  • STEP 5

  • Make sure both sides are even in the mirror, adjust if needed.

Check out this blog to know which insert is suitable for your outfit.

See Why Women Everywhere Love BOOMBA!

  • These are the most amazing thing ever. Used them at my wedding in Cancun, it was hot and humid and they stayed all day and night and I could probably still use them again. YES they really do add 2 cup sizes, I had people asking me if I got a boobjob, in a good way!🤣 buy them if you're on the fence!

  • Worth it 100%! Im a post breastfeeding mama and I haven’t ever been comfortable being bra-less, but these were an absolute game changer for spaghetti strap/strapless shirts and dresses! No annoying strapless bras which slip down, no nasty red marks all over, and the girls looked perfect!

  • I absolutely love mine! I have never in my life ever been able to wear a backless or tube top to save my life. My kids did a number on me! but this is no joke, I am in love. Just do it already you will thank yourself later when you get giddy about what you see!!

  • I have purchased twice now with you guys and I absolutely love them! I do recommend making sure you put the plastic back on after use as they are so sticky that they get super dirty and start to lose all their grip after a while. 10/10 recommend them!!! I can’t live without mine 🪩🫶🏽

  • I even wore these for seven days straight in seven different bathing suits while in the pool and ocean for hours on my vacation. and they are still good to use. Just love them. The endless hours of water did not ruin them at all.

Frequently Asked Questions

How to use inserts?

Preparation is key! Before using BOOMBA inserts, please ensure breasts are clean and dry. Any makeup, oil, lotion or other body products may hinder the inserts from sticking onto your skin properly. Put the clothing item on your body first, then place inserts onto the clothing item, then scoop breasts and stick onto the insert to secure.

How many times can I use BOOMBA inserts?

BOOMBA inserts are reusable up to 40 times. To prolong the life of your inserts, it is important to clean and reapply the protective films immediately after each wear to prevent dust and lint from sticking to it.

Which size is suitable for me?

Check out BOOMBA’s Size Guide to find out which size is suitable for your body. Please note that results may vary depending on breast size and shape. Results will be similar to a double push up bra. BOOMBA results work best with natural breasts.

Which insert is suitable for me?

Great question! This really comes down to what you are looking for!

A boost in volume? Our most padded insert, Ultra Boost, is perfect for users looking for a boost in size (up to 2 cups)! Designed for v-neck tops!

Cleavage in a sweetheart neckline? A shortened version of our Ultra Boost, the Demi Boost insert, is specially designed for low cut demi style clothing! Also boosting up to 2 cup sizes instantly.

Prefer a lift? Our lightly padded insert, Ultimate Lift, is perfect for girls looking for a natural looking lift!

Can I use BOOMBA inserts at the gym? Can I swim with them?

BOOMBA inserts helps you in a way you that can be use at the gym and swim with them on. Please make sure that your bathing suit is tight and to avoid big waves: if your bathing suits can't stay on, neither can our inserts!

What’s the proper way to use BOOMBA Inserts?

With BOOMBA inserts, it’s important to choose the appropriate top with your inserts. We always recommend structured tops that are made in a thicker material for best results (support in the chest area, not a loose t-shirt that hangs off the body, since the inserts are held up by the structure in your clothing).

Most bikinis, dresses and tops also work well as long as they are not too thin so that the color or shape of the insert shows through. A good guideline is that if the outline or color of your bra will show through in this top, BOOMBA inserts most likely will as well.

For some users, it does take a few tries to get it in the right position (just like getting your sticky bra to stop being lopsided), so we recommend checking out our quick tutorials for a better idea of how to use the inserts. We recommend putting the inserts on in front of a mirror to ensure it is even on both sides. You can adjust the level of cleavage according to your own preference. Just remember to scoop and stick, to ensure your cleavage stays put throughout the day!

You can see examples of some outfits here:

Picking an Outfit

✔️ Tight and structured bust area in the clothing
✔️ Thick materials in the bust area for a seamless silhouette
✔️ Sweetheart necklines and clothing with a support band under the bust
✔️ Sports bras and regular bras (turn them into push up bras with BOOMBA!)
❌ Very stretchy tops that cannot hold the inserts in place
❌ Loose and flowy clothing that cannot support any inserts
❌ Baggy t-shirt, knitted tops, most straight-across necklines
