Pilot Birdy Switch 0.7 mm Ballpoint Pen and 0.5 mm Mechanical Pencil (HSBN-50S)

Finally a tiny split pen/pencil that fits perfectly with my Moleskin notebook. The only thing that would improve it is if the pen side retracted somehow or there was another cover provided so you could cover both ends at once. As is there's always a pointy end so not great for pocket carry.

This tiny pen/pencil combination is surprisingly well designed. It even comes with a small plastic sleeve/card pen/pencil holder that easily slides into a large wallet or checkbook. It's not a pen that I would choose for most uses, but is amazing how it is small enough to fit into a checkbook cover and and doesn't bulge because the binding of the checks is as thick as this pen. I hate not having a pen when I need to write a check and this takes care of that problem.Besides being extremely useful, it also makes a fun conversation piece just for the novelty of it. The fact that it is both a pen and a pencil is quite a clever design.

This pen/pencil combo is a great idea. The size is great for Edc and any use actually. Here's the durability issue only took 4 days for the pen to stop working. The pen was my main use so no more edc for this pen/pencil combo.

I was missing informed, well not really mis informed, it just doesn't specify that you have to take cap off top to use the pen. I was hoping for something a little faster like a mechanical or similar. Also the pen is super thin, like half the thickness of a pencil. I have bigger hands and 8ts difficult to hang on to, slippery, but I like the metal casing. Other then that, writes great, both ends an durable product. I would recommend it, but I'd make known the thickness. I'm going to give 5 stars simply because i do.t feel a bad rating is appropriate considering most the bad is my preference.

Love this multi-pen for it's size, features, slimness, heft.Sadly it fell apart within first week: pen/cap unit flew off with force while it was just resting in hand - used a flashlight to find the little pieces but there are many very tiny pieces inside, impossible to put back together. Looked at pilot and even jetpen sites - there are no instructions for putting this back together, and the many pieces are teensy-tiny. Will try to call the company and see if they are able to send a schematic. :(

GREAT VALUE AND FUNCTIONALITY. Pen and pencil work perfectly. I can place in my journal/datebook as a bookmark that does everything I need. I LOVE THIS PEN AND PENCIL COMBO.

A clever and elegant design. It fits well in my pants pocket without breaking, falling apart, or stabbing my leg. Good for an active job involving squatting and scribbling. Unfortunately what it has in versatility it lacks in utility. It lacks an eraser for the pencil, and the ballpoint pen falls victim to the common problem of not working well at angles other than straight down. It's a good value for the price, but there's room for improvement.

Perhaps the one concern I have about this pen+pencil combo is that it is small enough to easily misplace. Though the size is one of the features I love about this writing instrument. The default is set to have the pencil side displayed at all times unless you switch the cap that discreetly hides the pen side. Unlike a multi-use writing tool, you don't twist a section of the writing instrument to switch from pen to pencil-- you remove the cap and switch it to the other side. The design is a little odd in this respect, but considering how small it is with the offered function, space was used efficiently. To refill the lead, which is a 0.5 mm size, you have to pull off the cap that conceals the pen tip side. Then pull out the pen cartridge refill, which is one small cartridge, to access the tube for pencil lead. Accessing the pencil lead tube is also how you replace the pen cartridges, as these are on the smaller side it does require the specific Pilot refill which will last a reasonable amount of time for short notes. For my purposes, it's nice to have a small pen and pencil in one writing instrument to keep in my pocket or purse. It's also nice to have around for travel journal entries.
