Common chain strap types are fixed (permanent) chain handles and removable/detachable chain straps. They are usually metal or metal‑tone (often gold‑tone) and are used for shoulder or crossbody carry.
Detachable chain straps let you switch a bag between handheld/top‑handle carry and hands‑free shoulder or crossbody wear, giving a 2‑in‑1 or multi‑way carrying option.
Interior storage varies by size and style. Many small crossbody or unstructured chain‑strap bags have no internal pockets, while others offer one main compartment plus features such as mesh pockets, credit‑card pockets, or a dedicated card slot.
Chain key charms serve both as practical keyrings and decorative bag accessories. They typically attach with lobster‑claw clasps or keyrings so you can clip them to handles, D‑rings, or zippers; they can hold keys or be used purely as ornamentation on purses, backpacks, or cars.
Keychain attachment chains are short (about 2–3 inches). Bag chains and crossbody straps are much longer; example listings show maximum strap lengths around 46.25–47.24 inches.
Chain straps appear on a range of styles, including mini top‑handle crossbody bags and structured mini purses, woven straw clutches or two‑piece sets with detachable metal chains, envelope/evening clutches with removable chains, oversized clutches, and small crossbody or vanity bags.
