"Kaalkopje" Pipe, Green
This pipe is first and foremost a keychain: folded up, it barely stands out among your other keys. Unfold it and the bowl of the pipe appears, ready to use straight away. The green colour and rounded shape reference the "kaalkopje" ("bald cap"), the Dutch nickname for a well-known mushroom with a bald, brown cap, translated here into a playful design rather than an actual mushroom.
Because of its small size, this pipe is mainly meant as a backup on the go: on your keyring, in a coat pocket or in your bag. It's not a replacement for a full-sized pipe with a large bowl, but it's handy when you don't want to carry your regular pipe everywhere.
Why a pipe as a keychain
This type of foldable pipe is typically made from lightweight metal and is popular as a small gift or novelty item, precisely because it doesn't stand out among your other keys until you unfold it. It's not a replacement for a pipe with a full-sized bowl, but it's a fun, discreet option when you're out and about without your regular pipe.
Usage
Unfold the pipe until the bowl stands upright, fill it with the amount you want and light it just like you would a regular pipe. After use, fold it back down to keychain size, and let it cool down first before storing it.
Maintenance
Clean the pipe regularly with a pipe cleaner or cotton swab to prevent residue build-up; this keeps the draw smooth and avoids a bitter taste. Store the pipe dry between uses.
