Adhesive Phone Wallet Grey

The Sinjimoru Spb2 is a stick-on card holder made from Lycra fabric that adheres to the back of a smartphone using 3M tape. It suits adults who want to carry three to five cards, cash or a security key without a separate wallet.

Flat-Surface Adhesion Limits

The built-in adhesive requires a smooth, flat rear surface to bond reliably; textured cases, curved edges or heavy silicone skins can prevent a secure hold. Cards stay in place through fabric elasticity rather than a mechanical latch, so they will not fall out unless deliberately removed.

Simple Peel-and-Stick Fitting

Installation consists of cleaning the phone back, peeling the liner and pressing the pouch into position for a firm bond. Misalignment on the first attempt is the most common issue because the adhesive grabs immediately and does not allow easy repositioning.

Questions about this item

Which colour should I pick from the 14 available?

Choose the shade that best matches your phone or case; all 14 colours use the same Lycra fabric and 3M adhesive, so performance is identical.

How many cards does the holder actually keep in place day to day?

The elastic Lycra pocket securely holds three to five cards or folded notes without them slipping out during normal use.

Will the 3M adhesive work with a textured or curved back?

The tape bonds reliably only to flat, smooth surfaces; textured, curved or heavily ribbed backs may not hold securely.
