It feels some plastic on the outside. There is a nice curvature on the lug side so that it sits perfectly around your wrist. The material is very soft. The shipment took 5 weeks. All in all, certainly no regrets.
Great strap. Arrived early and well packed. Item of good quality and that feels comfortable to wear.
Best rubber strap on AliExpress. The strap lock for the tail of the strap is a great design. Quality is excellent.
Cannot argue for the Superdeal price. Far quicker shipping than the well known Jeulong store.
Great material, highly recommend this store and this Strap.
