All Your Questions, Answered
1. Are Tani products authentic?
Yes — all Tani products come with our official tags and labels. Most are made with TENCEL™, so you’ll also see their co-branded hang tag — something only trusted brand partners can use. And just to be clear: we’re now the sole distributor of TANI USA, with no third parties involved. You’re getting the real deal, straight from us.
2. Can I return or exchange it?
Yes, absolutely. Returns and exchanges are free within 30 days of delivery — no stress, no hassle.
3. Care instructions?
Made with delicate, ultra-soft fibres:
  • Machine wash cold, gentle cycle
  • Turn inside out and use a mesh laundry bag
  • Avoid washing or tumble drying with rough items (like jeans)
  • Air dry for best results, or tumble dry low with care
