What the Sinji Pouch Basic 2 Is

The Viator Gear Sinji Pouch Basic 2 is a self-adhesive card holder that sticks to the back of a smartphone. It uses 3M tape to bond securely and holds three to five cards or folded bills in a stretchy nylon pocket. The slim profile adds minimal bulk while keeping essentials within reach.

Who This Suits and Who Should Look Elsewhere

Ideal for adults who want a minimalist wallet alternative that attaches directly to a phone with a flat surface. Not suited for buyers who need to carry more than five cards, prefer a detachable wallet, or use a device with a heavily textured or curved back that prevents adhesion.

The Specification That Decides Fit

The pouch relies on a built-in 3M adhesive strip for mounting. If your phone or case has a smooth, flat rear, the bond will hold; if the surface is uneven, the wallet will not stay in place.

Questions about this item

How many cards can the Sinji Pouch Basic 2 hold before it gets too tight?

It holds 3 to 5 cards plus cash or a key card; the elastic nylon Lycra stretches to keep them secure without loosening over time.

Does the adhesive lose grip or leave residue after months on the phone?

The 3M adhesive is designed for long-term bonding and removes cleanly; the pouch adds minimal bulk so heat from daily use does not affect the bond.

What must the phone or case surface be like for the pouch to stick properly?

A flat, non-textured back is required — curved, heavily textured or soft-touch finishes will prevent the adhesive from sealing.
