Jyarz started as a Kickstarter campaign and has become the gold standard for portable herb storage. The concept is brilliantly simple: a borosilicate glass inner jar provides a pure, non-reactive surface that won't leach anything into your herb, wrapped in a shock-absorbing silicone sleeve that makes it practically indestructible for daily carry. The wide mouth makes loading and scooping effortless, and the twist-on lid creates a genuinely airtight seal.
Jyarz vs Tightvac vs HERB GUARD
Each of these storage solutions serves a different purpose. The HERB GUARD is your desktop vault — large, dark glass, UV-protected, and humidity-controlled. The Tightvac is your rugged travel companion — unbreakable, vacuum-sealed, and cheap. The Jyarz sits in the middle as your daily driver: it's small enough to slip into a pocket or bag, tough enough to survive drops, and the glass interior means your herb tastes exactly as it should, no plastic notes or odour contamination. The coloured silicone sleeves are a nice touch too — I use different colours for different strains, making it easy to grab what I need without opening every jar.
The Capacity Trade-Off
The biggest limitation is capacity. Each jar holds roughly 3-5 grams, depending on how dense your herb is. That's perfect for a personal day stash, but it won't replace your bulk storage. The silicone sleeve also attracts lint and pocket dust if you carry it loose in your pocket — easily solved by keeping it in a bag pocket or pouch. At £14.99, it's a small investment for a well-designed product that does exactly what it promises.
