A step-by-step guide to assembling the Build-a-System Parcel for a weekend trip, from choosing your capsule size to locking the magnetic closure with confidence.

Quick answer

To assemble the Build-a-System Parcel for a weekend trip, start with one Large Capsule for bulk items, add a Mini Ink Parcel for small essentials, and connect them open as a tray before folding into dopp-kit mode. The zipper-less magnetic closure is what keeps the system secure, so align the magnets fully at every connection point before you pack.

Why a modular system beats a single toiletry bag for two nights

A weekend trip is the hardest case for a toiletry bag: long enough that you need real capacity, short enough that you resent carrying a full-size kit. A modular system solves that by letting you size the kit to the trip. The Parcel System is built around dual functionality — the bags open flat and connect into a tray, then close into a dopp kit. That means the same bag you pack on Friday is the one you unzip onto a hotel shelf on Saturday, without repacking into a separate tray.

What to check before you connect anything

Before assembling, confirm two things: the magnetic edges are clean and free of grit, and each bag is empty enough that the closure can meet. Magnets that are separated by a stray cap or a bulging tube will not seal, and that is the most common reason a leakproof container stops being leakproof in transit. Lay the pieces flat, wipe the magnetic strips, and only then start connecting.

Steps to assemble your weekend parcel

  1. 1. Choose your base module: Start with one large capsule, such as the DR Congo The Large Capsule, as the base of your weekend build. It gives you room for full-size bottles and the odd bulky item without forcing a second bag. Checkpoint: if your base module is already more than two-thirds full before you add anything else, you have chosen too small a base.
  2. 2. Add one small module for loose essentials: Attach a Mini Ink Parcel for the small things that otherwise roll around — contacts case, hair ties, a razor, or charging cables if you use the parcel for tech. Because it shares the magnetic connection, it rides with the base instead of shifting in your bag. Common mistake: overfilling the small module so its magnetic edge cannot sit flush against the base.
  3. 3. Open both modules into tray mode and connect them: Lay the bags open, flat, and connect them along their magnetic edges to form one continuous tray. This is the moment to confirm the magnets have actually engaged — run a finger along the seam and feel for a continuous join rather than a gap. Checkpoint: a visible gap at any connection point means the magnets are not seated; reseat them before packing.
  4. 4. Load the tray by weight, not by category: Put heavier items — full bottles, jars — in the base module and lighter items in the small module. Keeping weight low and centered in the base stops the connected tray from tipping when you open it on a hotel counter. Common mistake: distributing weight evenly across modules, which makes the connected tray top-heavy and awkward to open.
  5. 5. Close into dopp-kit mode and align the magnets: Fold the loaded tray closed and press along the magnetic edge until it seals. The zipper-less design means the closure is only as secure as your alignment, so press the full length rather than just the corners. Checkpoint: give the closed kit a gentle shake over a sink before it goes in your bag. If anything shifts, reopen and reseat the magnets.
  6. 6. Do a dry-run pack before the trip: Assemble the full configuration at home, close it, and carry it in the bag you plan to travel with. This catches fit problems — a module that is too tall for your weekender, or a connection that pops open under compression — while you can still change the build. Next step: if the build feels bulky, drop the small module and carry fewer items rather than forcing the closure.

Product facts that shape your build

  • The Parcel System: The Parcel System bags are designed with dual functionality — a tray when open and connected, and a dopp kit when closed — with a zipper-less magnetic design for secure travel and visibility. You can pack and unpack the same bag instead of transferring items into a separate tray, which cuts down on forgotten bottles at checkout.
  • DR Congo 🇨🇩 The Large Capsule: The DR Congo The Large Capsule is a large, leakproof, magnetically closing capsule designed for secure travel storage and daily essentials. Its large size makes it the natural base module for a weekend build when you are carrying full-size bottles or several small items.
  • The Mini Ink Parcel: The Mini Ink Parcel uses the same dual-function, zipper-less magnetic design as the rest of the system, opening as a tray and closing as a dopp kit. Because it shares the connection system, it can attach to larger capsules rather than floating loose in your bag.
