Long Envelope

userguide

If you purchased the self-assembling DIY version, please read the following assembly instructions carefully. If you purchased the finished product, you may proceed directly to the Product Use & Care section for daily maintenance information.

Assembly Instructions

Although the assembly process is fully reversible and allows repeated adjustments, we recommend carefully reading all instructions beforehand to achieve the best assembly quality and final form.

Dedicated Screw

  • Please use the dedicated Ring Spanner provided to protect both the screws and leather surface.
  • During assembly, each leather hole must correspond to the correct screw length. Please refer to the screw numbering shown in the assembly video.

  • Screws should be tightened firmly until they lightly secure the leather surface. If a screw becomes difficult to tighten, remove the nut and check for leather debris or foreign particles in the thread before reassembling.

  • Although the screws are reusable, the anti-loosening coating on their surface will gradually wear down with repeated assembly and disassembly. Frequent removal is therefore not recommended.

  • Do not apply lubricant or oil to the screws, as this may damage the anti-loosening coating.

Dedicated Ring Spanner

  • The dedicated Ring Spanner reduces assembly effort, provides appropriate torque, and features a soft-contact surface to help protect both screws and leather during assembly.

  • Both sides of the Ring Spanner are covered with soft gray and black protective layers corresponding to different screw types. Please follow the gray/black side indications shown in the assembly video for the best experience.

Sliding Spanner

  • The Sliding Spanner is designed to reach into narrow interior spaces of the product to prevent the internal screw from rotating. It should be used together with the Ring Spanner to tighten the screw externally during assembly.

Protective Paper Spacer

  • The protective paper spacer is used to prevent accidental scratching caused by the rotation of the Ring Spanner during assembly.

  • Although the Ring Spanner already features a soft-contact surface, using the protective spacer provides additional isolation and protection.

  • The spacer is disposable and intended only for assembly use. Once assembly is complete, it can simply be removed from the leather product.

Guided by the assembly tutorial video, you can gradually unlock the journey from a single piece of leather to a finished leather product. Feel free to pause, replay, or slow down the video to match your own assembly pace.

Product Use & Care

Vegetable-tanned Leather Care Instructions

  • The leather surface of the Envelope collection has been treated with a water-repellent coating that helps prevent oil and moisture from immediately penetrating the leather’s natural pores. However, this treatment is not intended to make the interior of the wallet waterproof. If exposed to water or oil splashes, wipe the surface clean with a dry cloth as soon as possible to avoid permanent marks.

  • The natural pores of the vegetable-tanned leather have been sealed through the water-repellent treatment. For this reason, applying leather oil during maintenance is not recommended. Regular care can be done simply by gently removing surface dust with a soft dry cloth or soft brush to maintain the leather’s smooth appearance.

  • If the leather becomes stained with more stubborn grease or dirt, wipe gently using a well-wrung damp cloth. After cleaning, place the product flat in a cool, well-ventilated area and allow it to dry completely before continued use.

  • More difficult stains may be removed using a soft eraser. Do not use hard or abrasive erasers, as they may damage the water-repellent coating.

  • Do not use alcohol, stain removers, paint thinner, or any type of solvent on the leather surface, as these substances may damage the water-repellent coating.

  • Avoid contact between the leather surface and sharp objects or excessive pressure. If self-repair or screw replacement is required, please use the official Envelope tool set provided by Studio Smoll.

Screw Care Instructions

  • The screws are coated with a special treatment designed to reduce the possibility of loosening.

  • Although the screws are reusable, the anti-loosening effectiveness provided by the special coating will gradually decrease with repeated assembly.

  • Repeated disassembly and reassembly of the screws is not recommended, as this will eventually cause the anti-loosening function to fail. Because the coating is consumable in nature, we are unable to provide warranty, repair, or recycling services for used screws. If excessive degradation of the anti-loosening performance affects product usability, replacement screw sets are available for purchase from us.

  • The screws do not require any lubricating oil or lubricant, as this may cause the anti-loosening coating to fail.

  • All screws included with our products are made from stable, acid- and alkali-resistant 304 stainless steel and require no special maintenance. If dirt or dust accumulates, simply wipe clean with a dry cloth. If using a damp cloth, avoid contact with the leather areas.
