What women say
“Three days after subscribing, the surprise box was already with me. Excellent underwear, very pleasant to the touch—now I don’t have to waste time searching for comfortable briefs. Thank you! P.S. A special thanks for the cute little gift!”
“Ik wou dat ik eerder van deze service had gehoord! Ik kan niet wachten op mijn nieuwe slips. Ik vind het fijn om elke maand nieuwe slips te krijgen, ik hoef me geen zorgen te maken dat ik op zoek moet gaan naar het juiste ondergoed, ze komen één keer per maand met de post en ik heb altijd veel opties in mijn garderobe om uit te kiezen.”
“Super quick delivery and great product! I love how it feels on skin. The thought put into the packaging made me smile, thank you :)”
