How the mechanism works
Each numbered wheel sits on a shaft with a ring that has a notch. Behind the door is a bolt with a finger under each ring and a tongue at the bottom. The handle lifts the bolt only when the notches of all rings are at the bottom — that is, when the code is set. If even one wheel is off its number, the bolt is blocked, the tongue stays in its pocket and the door won’t open.
The handle has a slip clutch: it can’t be forced. The code can only be changed from inside, with the safe open.
A slot for coins and notes
The 28 × 3.4 mm slot takes every circulating NBU coin, including the 10 hryvnia, and notes folded lengthwise. Under the slot is a labyrinth: you can’t shake the coins out just by turning the safe over. The “Classic” holds about 469 ten-hryvnia coins.
Who to give it to
- A teenager saving up for a dream — the “Classic” with their name.
- A family — several “Drawers” in different colours with names, each with its own code.
- For a birthday — the “Cash gift” with notes inside and the code in a card.
Limitations
- It keeps out the curious, not burglars: the body is plastic and the code can be found by trying combinations. Not for documents or valuables.
- Forgot the code — there is no spare key. Write the code down and keep it separately.
- The safe piggy bank is a gift for teenagers and adults 14+, not a toy: it has small parts, keep away from children under 3.
- PETG softens at around 66 °C: don’t put it on a radiator or leave it in a car in the sun.
