Oh my this is super cute!! I put three pencil mechanisms in mine, and I filled them with Uni NanoDia Color leads in mint blue, pink, and lavender to match. I actually like this style body a lot more than the 4 color Uni Style fit body if you are going to completely fill it with pencils. In the 4 color bodies with the lead advance button, when you click the button on top, the other pencil mechanisms inside the body make small marks and scratches inside of the nose cone. In this pencil, that does not happen, so your pen body will stay looking new. The little selection levers are all big enough to comfortably push to advance the lead (they even stick up a little higher than the ones in the Uni Color 3), and it's a lot slimmer than the Uni Color 3 which is one of my favorite multi-pencils. When completely full of pencil mechanisms and leads it weighs 12 grams, which is two grams lighter than the Uni Color 3. The only thing it doesn't have compared to the Uni Color 3 is the eraser, but I usually use a big eraser, not the eraser on the back of my pencil. It also rattles slightly more than than the Uni Color 3 when you shake it, but it's not very noticeable. A lot of multi pencils rattle a little bit, and it's not as loud as the Rotring Trio Pencil which has weights for the gravity selector mechanism inside. Uni only makes pencil mechanisms in 0.5 mm for the Style Fit, unlike Zebra who has 0.3, 0.5, and 0.7, but Zebra stopped making bodies that can take more than one pencil mechanism, so the Style Fit is one of only options besides the Pilot Coleto if you want an all pencil multi pen.

I missed out on the Zebra Preill multi pen body in white with polka dots. This pen came close with polka dots and Mickey silhouettes. it is easy to load. I like the clear section because you can see the colors, and that makes it easy to choose the color to write with. I have a metal version which doesn't let you see the ink colors. I like it too, but I prefer the ease in seeing the ink.

Broke after a few months of use. The clear part of the body cracked when I was closing it back up replacing the ink.

This pen body is adorable, and it’s not too thick. I love how many options I have with the style-fit line! The subtle Disney pattern on this one is cute without being over the top.

I love the slim barrel design. So lightweight and I can have 3 color options to write with. And so cute too ❤️
