Schmidt 635 Mini D1 Ballpoint Refill Medium, 4 Pack, Black (SC58149) | D1 Standard Size for Multifunction & Mini Pens | Premium Stainless Steel Tip with TC Ball for Smooth Writing

Very happy with my refills. Works perfectly for my Swarovski chrystalline pen. Writes smooth with deep black ink. Very happy with my purchase.

Bought this specifically to replace the dried out ink cartridge for a lego pen. This is a pen that has lego pieces that kids can customize on the top. Writes clearly and as expected for ball point pens.

Product picture shows 4 colors in the package but I was sent all black ink. I didn’t realize that the color of the ink is indicated by a mark on one of the 4 colors, instead of the package containing all 4 colors.

The D1 refills I received were high quality and the price was quite reasonable. Package arrived within the promised time period but the time frame itself was a bit on the slow side. Luckily I was ordering in advance of need, so that wasn't an issue for me. But if you need your refills urgently, you might want to pay attention to delivery time frame and plan on getting them at the far end of that timeframe.

The packaging was not as pictured - shown on Amazon as a retail flat cardboard shelf-hanger pack - but the actual products were authentic Schmidt refills as pictured and were better packaged, in my opinion. The four cartridges were packed in a plastic bag inside a resealable plastic zip lock bag with the owner's card and rigid insert to protect the cartridges during shipment. These ink refill cartridges work very well and exactly fit my pen that uses a D1 size cartridge. I prefer the packaging that was sent as it is smaller than pictured and stores better in my desk drawer and is can be tightly re-sealed after opening to preserve the unused cartridges. This is a very good value and I recommend this seller.

I was recently gifted this pen but the ink was drying. I looked up a replacement and this works great with my Swarovski pen!

Nice lines and good ink. Although it fits into the TEC Accessories Pico Pen, it will not stay. The magnetic mount pulls it out. There's not a 'step' in the cylinder like the original refill has.

Got my wife a Swarovski glitter pen as part of her anniversary present a few years back, and she loves using it, but she stopped because the pen cartridge ran out. Had I known this, I'd have bought these refills ASAP, as it's exactly what was needed. Just use a fine tip screwdriver to remove the plug, pull the old cartridge, pop the plug cap onto the new one and reinstall. Presto, she's writing with her favorite pen again.

Muy bien producto

Arrived yesterday. Hopefully they’ll be easy to replace as needed. I have a beautiful pen so having replacements makes sense

Perfeito. Do jeito que eu precisava!!!

Very unique refill and it fits perfect. Note that it does not come with the black cap so DO NOT THROW OUT your old refill you will need it.

Great to further the life of my mini pens that fit into a small wallet. Quality and quick shipping was great
