This isn't quite the same as the old optic swap tool which was an entire case with a black bottom with 3 spokes on the inside to remove the older optics. This newer version is as pictured one solid piece of plastic. The 3 spokes or knobs are on the bottom outside to remove the older optics such as double glass and single glass optic. It's solidly made but if I drop it I can see that a knob could crack off thus I ordered 2. It works removing the older optics that use the 3 knob or spoke removal tool as I have a double glass optic and it removed it nicely from a Composer Pro. I tested my double glass optic and it fit the cover. At $10 a piece a little pricey but I guess if you need it worth the cost and it is well made and less bulky than the older design. I have uploaded some pics. You can see it attaches to the back half of the optic and the lens cover serves to protect the front lens. You could also use a microfiber bag or small neoprene bag to protect you optic but I needed the removal tool so decided to purchase these as I also bought a Sweet 80 optic from Lensbaby. Lensbaby was kind enough to gift a small micro fiber cloth with my Sweet 80 which I can store in the end of the cover. Happy with purchase and I hope this helps other Lensbaby enthusiasts using optics.
