Product Description
Unfortunately, I would like to inform my friends who are interested in PSVANE KT88 that this product will no longer be produced until April 2024. Now that our inventory is almost sold out, we have specially launched its PLUS version, PSVANE KT88-PT. The price is slightly higher due to three improvements:
1. Ceramic pipe seat, impermeable, with good moisture resistance and durability
2. Cathode: Gold plating for better conductivity
3. Packaging is more environmentally friendly and safer.
I hope everyone can enjoy our new products more.
All products in our store are sourced from real photos and videos, ensuring authenticity. Please rest assured to purchase and ship within 48 hours. If there are any after-sales issues, please contact me as soon as possible (open the AliExpress software and contact me through the seller dialog box). I will reply to you as soon as I see the message. Our product comes with a quality issue warranty within 15 months. Please keep the outer packaging of the product so that we can track and investigate it. Thank you.
