Mini Pocket Scale, Item: MM-338, Size: 65x34x15mm, Color: Black, Weighing Unit: g/tl/ct/dwt, Capacity: 100g/0.01, 200g/0.01, 500g/0.01, 500g/0.1, Power: CR2032, Packing: 400pcs/ctn
The MM-338 hides a full digital scale inside a car-remote housing: 65×34×15 mm, a stainless platform under a sliding black cover, and four capacity boards — 100 g / 200 g / 500 g at 0.01 g plus a 500 g / 0.1 g general board. On a retail counter it reads as a key fob, not a scale — which is exactly why it sells.
| Capacity | Resolution | Best for |
|---|---|---|
| 100 g | 0.01 g | Gemstones, coins, powder portions |
| 200 g | 0.01 g | Jewelry lots, small parcels |
| 500 g | 0.01 g | Bulk jewelry, scrap gold |
| 500 g | 0.1 g | Food portions, general trade |
Same housing, same two-key layout on every board — pick the range per market and mix boards in one carton.
g for general weighing, ct for stones, dwt (pennyweight) for precious-metal trading, tl (tael) for the Chinese gold trade. One key cycles all four — no conversion chart at the counter.
The slim profile is only possible because it runs on one CR2032 coin cell (included) — no AAA barrel inside the shell. End users can find a CR2032 anywhere; the slide-off back cover swaps it in seconds.



Closed, it is a 15 mm fob that fits a pocket or tool bag. Open the cover and the stainless platform takes rings, loose stones and small parcels. A pouch kit (zip case, pouch, cleaning cloth) and a tweezers tray set are available for retail gifting.
