Ultra Boost Inserts come in a rounded-triangle shape, which makes them perfect with v-neck necklines and bikinis. We recommend that you choose clothes that are structured with thick fabric in the bust area. A support band under the bust will be ideal for support. The clothing should also be tight and not stretchy, otherwise, the top will not be able to push up against the inserts.

BOOMBA Inserts have adhesive on both sides to stick to your skin and grip onto clothing, removing the need for bras. You just have to place them on the inside of your structured top first. Next, scoop your breast to the desired height and position, then stick the inserts onto the breast to secure.

Due to sanitary reasons, ALL sticky inserts, bras, nipple covers, accessories, and promotional items may not be returned for a refund, credit, or exchange unless you have received damaged, defective, or the wrong item(s).
