Terrarium Koski Ceramic Air Plant Holder

A ceramic cup under three inches in diameter fits beside a keyboard without crowding the mouse pad. The Koski at 2.5 inches holds one small tillandsia or a pinch of moss, weighs enough to resist accidental nudges, and occupies less desk area than a standard sticky-note pad. Our office coordinator, Nessa, tested a dozen miniature planters across a row of workstations and reported that the Koski was the only one nobody complained about bumping.

The cup measures 2.5 inches in diameter. Height varies slightly by glaze batch but averages around 1.5 inches from base to rim. Our quality inspector, Harlan, checks every batch with a caliper — not because the variance matters functionally, but because he owns a caliper and believes in using what you have.

Yes. The flat ceramic base sits stable on any level surface — dining tables, side tables, bathroom counters, bookshelves. The weight prevents tipping from vibration or a passing elbow. Our event planner, Marta, positions a row of Koskis as place markers at dinner parties, each holding a different tillandsia variety, and guests take them home as favors.

Compact tillandsia species — ionantha, caput-medusae, brachycaulos, and kolbii — fit the Koski cup without overhanging the rim. Preserved reindeer moss or dried sphagnum also works as a decorative fill. Avoid succulents that need soil depth because the Koski is too shallow for a proper root-and-gravel layer. Our buyer, Suki, stocks ionantha alongside the Koski as a bundle because the proportions match right out of the box.

Mist the tillandsia two to three mornings per week, enough to dampen the leaves without pooling water in the ceramic cup. Soak the plant in a separate container for twenty minutes once weekly, then dry it upside down before replacing. Our warehouse associate, Dieter, mists every Monday, Wednesday, and Friday at eight sharp and considers the routine non-negotiable, which his coworkers find endearing and slightly militant.

Built for it. The ceramic body absorbs ambient warmth from nearby electronics and redistributes it gradually, which stabilizes the microclimate around the plant in air-conditioned offices that run cold. The cup is compact enough for cubicle ledges, monitor risers, and that narrow strip of desk between a laptop and a coffee cup. Our IT lead, Reggie, has one beside each of his three monitors and claims they improve his code, though he provides no supporting data.

Place the Koski on a stable surface near indirect light — beside a window, under a desk lamp, or on a shelf that catches ambient brightness. Drop a small tillandsia root-end down into the cup and let the leaves fan outward above the rim. No soil, no gravel, no accessories required. Our receptionist, Yuki, set hers up in under ten seconds and has not adjusted it since, which is either exemplary low-maintenance design or simple indifference.

Production started in 2012 at the Chive studio. Koski was the company's first secretary, and she earned the naming rights by simply asking whether doing a good job came with perks. It did, and the perk was a ceramic cup with her name on it that now ships to offices, desks, and kitchen windowsills around the world. She still works here, and she still has the original on her desk.
