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. 

  • Works with 34A to 34DD (Refer to the size chart)
  • Boost up to 2 cup sizes 
  • Prevents nipple slips in low cut tops
  • Insert stays put and keeps clothing in place
  • Sweat & water resistant
  • Interchangeable between outfits, no sewing required
  • 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, they cannot stay up by themselves. It is crucial to wear them in tight, structured, and fitted tops. 

Ultra Boost (cocoa) in size B may come in either the gift packaging or the eco-friendly packaging. For every product sold in our eco friendly packaging, BOOMBA will be donating $2 towards the charity of the month.

"My favorite thing about these inserts is that they don’t go everywhere. I like them because they’re sticky on both sides. I know that’s double protection, they’re not going anywhere."

Gave me the boost of confidence I needed!

My sister is getting married and she picked out the same dress for all her bridesmaids. The only issue was that I am quite small in the chest area and couldn't really hold up the dress that well. I bought the ultra boosts and they arrived today and they are amazing! I am a 34B and after the inserts I look like I am at least a D, I love how I look in my dress so much more and I also like that it keeps my boobs in place and so secure so I don't have to worry about exposing myself in any photos lol. I am super happy with my purchase and can't wait to wear them!

Better than I expected

I expected this to be as described but to my surprise they are even better than I thought it would be! I have been looking for something like this after losing a lot of weight (over 20 pounds!) and losing over a full cup size, so I no longer had the full breasts I once had. I have been looking online for something to make my boobs look bigger in bathing suits as I am going on vacation next month for my birthday. These inserts are very sticky but they are not so sticky that it hurts when you take them off. They are quite light considering how much padding there is. They looked really good in my bathing suit without being too over the top. I love the storage box that it came in, not only is it super cute I love that I have somewhere to store them away from my cat and his million of cat hairs flying around my apartment. I love these inserts and feel like they are very well made, I love that they included a thank you card along with instructions. I also spoke with them before my purchase because I was not sure which size to get as I lost a lot of weight and am now in between sizes. The customer service was really helpful and friendly, they explained and answered all my questions which I really appreciated.

so happy!!

THESE INSERTS MAKE ME SO HAPPY! I lost a bit a weight and so my boobs shrink A LOT. My favorite bikinis were now too loose on the top and bottom, which really sucked because I spent so much money on them before. I just kind of left them in the corner of my drawer. I initially bought these inserts for my summer tops. But I tried them in my old bikini tops to see if it would fill them out more and they were PERFECT! Not only did they fit me perfectly, they also kept my bikini top in place and felt really secure which I love. I went kayaking with my bf and they stayed in place even when I got sweaty. They did make my boobs look a lot bigger, which I am not complaining about lol. My bf was low-key drooling the whole day lol. This is my favorite purchase I made all year!

Hi Love :) Thanks for reaching out and leaving your feedback! I have just checked for your order and there seems to be none under your name or email. However I did see an account made but no purchases, so your order may not have gone through successfully! If there was a mistake, please email contact@getboomba.com with your order confirmation email and I will be able to track down your order for you :) Please also note that ALL inserts are currently on pre-order, so they will NOT be shipped out until the date specified. Thank you for your support and patience! >3 -BOOMBA team :)
