I've purchased three vouchers. The description stated that they can be used for a single treatment, but they can be used for multiples. It turns out that when I wanted a treatment, I could only use two vouchers for one treatment. So, it was a waste and I actually lost out on one voucher. The other voucher can be used again, but at the same Waxhaus branch, and I don't necessarily have time to go to Sentul, as I'm more often in Jakarta. 🙏🏽
But the service during the treatment itself was good.
