Surface Slim Pen first generation I bought a Surface Pro 3 years, and the pen outlived it. The battery went on the pro, but the pen lives on! *Made for the Surface Pro X and Surface Dou. See photos for pictures from Mircosoft. The pen worked great. My pro died 2 months ago, so I haven't been able to test it in that time frame. I did just plug it in, and it's needs to be charged (per the red light charging indicator in the last photo). It will glow white, also shown when done. I used this pen for digital art, I noticed I did nibble on it accidentally at one point, but it has never affected it. Interesting fact, art historians believe that Van Gogh put the paint covered tip of his paint brush in his mouth, and they believe he may have given himself lead poisoning. It makes sense! So guilty as charged. Sold as is, please check the specs of Mircosoft Surface and all photos before purchasing. Comes from a smoke-free, pet friendly home. Also! ♡Top Rated Seller ♡ Fast shipper (same day shipping or day after depending on time, or whether or not the post office is open) ♡ POSH Ambassador ♡ I am a professional artist and sometimes will sneak in a fun little drawing. Lastly! MAKE AN OFFER. I go off other sites, and this when pricing these. If you want it but you think the price is not to your liking, make that offer! The worst that can happen is a no.
