PROTÉGÉ PAR BREVET
La coque la plus rembourrée du marché. C'est la solution idéale pour obtenir un effet de surprise. Booste instantanément jusqu'à 2 tailles de bonnet. Recommandé pour les hauts avec une structure au niveau de la poitrine.
- De forme triangulaire, idéal pour les hauts à taille basse en V.
- Augmente jusqu'à 2 tailles de bonnet
- Adhésif double face pour plus de sécurité
- Résistante à la transpiration et à l'eau
- Aucune couture requise et interchangeable entre les tenues
Nos coques ne sont pas destinés aux personnes ayant une peau sensible ou fine, ni aux femmes enceintes ou qui allaitent.
Contrairement à un soutien-gorge collant qui est soutenu par l'adhésif, les coques BOOMBA sont soutenues par les vêtements et ne peuvent pas rester en place toute seules. Il est crucial de les porter dans des hauts moulants, structurés et ajustés.

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.
