Trodat Printy 4912 Self Inking DIY Stamp Kit – Black Ink, 3/4” x 1-7/8”

Before I found this, I almost spent much more on some custom stamps to keep track of various recurring school tasks in my analog planner, as writing out the same 4 deadlines over and over again each week for 15+ weeks was getting annoying. After unboxing this, in ~15mins, I was able to stamp out all of my deadlines for the rest of the year, with as much customization/detail as I needed. The size of the text was perfect for my needs - I used the larger font and it worked perfectly for the weekly layout in my B6-sized planner (and I love that I can go smaller for extra wordy stamps). I'm really glad to have this tool in my arsenal for future courses or just "life admin" recurring reminders. It's awesome and WAY worth the price!

Customizing a stamp was so handy during wedding process. I didn’t want to hand write every thank you cards return address, so I made it my address. We ended up moving and it was so nice to not have to buy a second stamp. Just rearrange the letters and voila!

This is the third time I’ve purchased this set. Not because the other ones were ineffective but because as I have told people how versatile this is, they are wanting one as well. I have one to use at home and one to use at the church. As a notary signing agent, I have to repeatedly write the month on documents of greater than 100 pages. I started to purchase custom stamps for each month (except the months with few letters) but that was getting expensive. I got this to easily change the months each time a new month rolls around. I make the stamper the current month and then change it out as the next month rolls around. This is great for that and much less expensive than trying to purchase custom stamps for each month. At the church, we send out different mailings throughout the year and we include return envelopes with them. Previously, we were placing labels in the bottom left corner of the envelopes so that we could keep track of what the returned envelope was for but now we just stamp the envelopes as needed. It’s very easy to change the wording, using the stamp for that need and then change it up for the next project. It comes with a good supply of upper and lower case letters as well as symbols and numbers. Each impression is clear and crisp. I would definitely recommend this set and more than likely will be purchasing it again for other needs.

I just received the stamp at time of making this. It arrived in a matte green printed paper packaging, so no waste there. Inside there was: -Stamp -2X Stamp symbol pads(different) -Black ink pad (woth removable cover) -Info booklet -plastic tweezers -label paper The stamp stamps smoothly without much force. It has a lock slider that can either hold the slot where the ink pad goes into open, or hold the part of the stamp you put the letters on at the bottom of the stamp(where it meets the paper) so you can change the symbols. The stamp symbols consist of 2 sets, one has smaller letters than the other. All letters are capitalized but the 2 sizes makes it so you can still distinct larger and smaller letters. I recommend useing the provided tweezers as it is difficult to more the letters with out hand. The letters stay in the stamp well and shorter words and songular symbols can be slides in the stamp by hand. The ink pad works well and it made solid stamps on cardboard. It doesn't feel cheap either. 7/10 based on it's ability to repeatedly ink surfaces with customizable symbols. good stamp. Higher numbers will require stamp technology that I have not seen yet. (A stamp with customizable letters that does not move smoothly or ink evenly would get a 4/10) Remember, 3 stars is ok, 4 stars is good, and 5 stars is amazing.

Love this! So much easier than I thought it would be to set it up. The letters snap in super easy and stay in place. I use it for coin envelopes and have stamped about 300 envelopes so far and every one has been just about perfect every time. Ones that weren't was because I was in a hurry. Just make sure you put each letter for each word right up flush next to the previous one.

This thing is awesome. Ink is super dark and easy to stamp. Multiple size letters make letters super easy to read and doesn’t smudge or leave any other residue. It’s also just cute. I use it to stamp my tag onto all of my creations.

decent stamp but it is not user friendly at all and the instructions are impossible to understand

Works perfectly. I bought this for my journal/calendar making as I have terrible handwriting but would like nice headings. Picking each letter out and placing it on the device itself was easy. It come with the ink cartridge, tweezers, two sets of letters I believe 3 and 4mm sizing. I have some paper and washi tape for leveling and placement on my stamp (see images). The letters are small but perfect for my use case. The stamps are legible and do not get fuzzy unless you stamped it too hard or moved when stamping down. The 2026 in my photo is the large font and the days of the month are the small font for sizing. I would highly recommend this product.

A qualidade da impressão do carimbo não é muito boa e o estilo da fonte não pode ser personalizado. Além disso, a depender do que se escreve, faltam caracteres às vezes.

I have a small Etsy business and this thing is a lifesaver. I use it for my return addresses and it's super convenient and stamps well 99% of the time. Letters come out clear and sharp. It's a bit of a pain to set up and I don't plan on changing the text anytime soon, but if you wanted to switch up the text frequently, I wouldn't go this route, or I'd just buy 2.

excelente, me encanta que lo puedo diseñar sola y cambiar cuando quiera

The stamp became stuck in the 'stamp down position' after only a handful of uses. I got to stamp maybe 15-20 cartons for my small business before the mechanism or spring inside became jammed and is now unable to return to it's original position. Garbage.

Bien reçu aujourd'hui 3 octobre 2026. Le produit est conforme à ma commande. La cartouche d'encre étant incluse, les essais de cette dernière ont été concluants. Produit à recommander pour qui aime bien les (petits) travaux de précision. ;)
