CryptoSafe Pen
Pairs well with
The CryptoSafe Pen is a tungsten carbide scribe for engraving your seed phrase onto a CryptoSafe Lite steel plate. No hammer, no punches — just write.
Why tungsten carbide
Tungsten carbide is hard enough to cut into stainless steel and keep its point. You can engrave a full seed phrase, and then another, without the tip going blunt.
Stamping or engraving?
- Engraving with the CryptoSafe Pen is quiet, needs no hammer, and lets you write freehand. Marks are shallower than stamped ones.
- Stamping with the CryptoSafe Stamp and Hammer gives deeper, more uniform characters, but needs both tools and a firm surface.
Both outlast paper by a wide margin. The CryptoSafe Pen is the simpler option if you want one tool and no noise.
Works with
The CryptoSafe Lite steel plate, and any hardware wallet whose recovery phrase you want backed up in steel — Ledger Nano S Plus and Nano X, Trezor, Tangem, SafePal, D'CENT, CoolWallet and KeepKey among them. Tangem is seedless by default, so this applies if you have chosen to create or import a seed phrase.
Why engrave rather than write
Ink fades, paper burns, and in Thailand termites eat it. An engraved steel plate keeps your words readable through heat, water, humidity and time.
Common questions
Does it need a hammer?
No. You engrave by hand, like writing with a pen.
Is it as durable as stamping?
The plate is equally durable. Engraved marks are shallower than stamped ones, so write firmly and go over each letter more than once if you want a deeper line.
Can I use it on the CryptoSafe Pro or Capsule?
Those use pre-made letter tiles and need no marking tool. The CryptoSafe Pen is for the CryptoSafe Lite plate.

Before you buy
Still deciding? Compare every model side by side, or ask us — we answer in Thai and English.
Are your products genuine?
Yes. Every device we sell is new, sealed and sourced through official distribution. SIAMBC has been Thailand's hardware wallet specialist since 2016 and has a physical store in Bangkok you can walk into.
This matters more than it sounds. A hardware wallet bought from an unknown marketplace seller can arrive already set up by someone else, with a recovery phrase they know. It is the one purchase where the seller genuinely matters.
How long does delivery take?
Orders normally arrive within 1 to 3 business days, depending on where you are — faster if you are in Bangkok.
Need it today? We can send it by Grab or LINEMAN for same-day delivery. Call us or message us on LINE to arrange it, pay by bank transfer, and it goes out immediately.
You are also welcome to collect from our Bangkok store.
Can I collect from your store instead?
Yes. We are in Thawi Watthana, Bangkok, open Monday to Saturday, 9:00 AM to 5:00 PM. You are welcome to come in, see the devices in person and ask questions before you buy. We answer in Thai and English. Find us here.
What warranty do I get?
Hardware wallets come with a 1-year warranty, and claims go through us rather than an overseas support queue.
If a device arrives faulty, we replace it with a new one straight away. No forms, no waiting on the manufacturer.
CryptoSafe steel backup products are the exception: they are sold without warranty and cannot be returned or exchanged, as stated on those product pages.
How can I pay?
Credit card, bank transfer, or cash on delivery. You can also pay in person at our Bangkok store.
Will you help me set it up?
Yes. Bring your device into the shop and we will set it up with you — creating the wallet, writing down the recovery phrase properly, and checking you can send and receive before you leave.
Setting up a hardware wallet is the step people most often rush, and it is the one that matters most. If you would rather do it at home, ask us anything on LINE.
Which model should I choose?
It depends on the phone you use and what you are protecting. The most common mistake is buying a wallet that does not work with your phone — the Ledger Nano S Plus does not support iPhone at all, and most Trezor models are view-only on iOS.
Compare every model side by side, or ask us. We will tell you honestly which one fits.
What happens if I lose my hardware wallet?
Nothing, as long as you still have your recovery phrase. The device only holds the keys — buy any compatible wallet, enter your phrase, and your crypto is back.
The real risk is losing the phrase itself. That is why we suggest keeping it on steel rather than the paper card in the box. Paper burns, floods, and in Thailand termites eat it.
Will anyone ever ask for my recovery phrase?
No. Anyone who asks for it is a scammer, without exception. Neither SIAMBC nor any manufacturer will ever ask for your recovery phrase — not for a warranty claim, not for identity verification, not for a firmware update. Whoever has those words owns your crypto, and it can never be recovered.
