FAQs

How do I use BOOMBA Inserts?

Preparation is key! Before using BOOMBA inserts, make sure your skin is clean and dry. Avoid applying makeup, oils, lotions, or other body products, as these can affect the adhesive’s ability to stick properly.

Start by putting on your clothing item. Then, place the inserts inside the garment without touching the skin. Finally, scoop your breasts to your desired position and stick the insert along with your top onto your breast to secure.

How are BOOMBA inserts different?

Unlike traditional inserts, BOOMBA's inserts are sticky on both sides, which means it sticks to your clothing and to your skin for extra security. Preventing nipple slips and easily staying hidden under clothing.

BOOMBA inserts require no sewing to stay in place! Just stick to your skin and to your top! They are easily interchangeable between different tops and dresses.

How many times can I use BOOMBA Inserts?

BOOMBA inserts are designed to be reusable for up to 40+ wears with proper care. To extend their lifespan, gently clean the inserts after each use and reapply the protective films right away. This helps prevent dust, lint, and other particles from sticking to the adhesive surface and ensures long-lasting performance.
