Need an eye piece Dia 66M F 700 MM
The two popular eyepiece sizes are 1.25" & 2 in.
Older 'scopes may have 0.96 in eyepieces.

You will NOT get 525 power from that small telescope. Yes I know the box said that but it was a lie.
An eyepiece might cost as much as you paid for the entire telescope. NEVER buy a telescope that advertises magnification on the outside of the box.
Here are some eyepieces:

You mean an EYEPIECE?
Several companies sell eyepieces for telescopes. They come in .965, and 1.25 inch sizes. Measure the hole in the telescope.

Your scope is 60mm not much bigger than a pair of 10x50mm binoculars the most magnification it will give is about 100 power or less.
Eyepieces come in 3 sizes, .965 inch, 1.25 inch, and 2 inch. Measure the hole in the focuser and buy the correct size. Here are two retailers:

Most telescopes use a standard fitting eyepiece with a 1.25 inch outside diameter barrel. You can measure the mount where the eyepiece goes to make sure that yours is this size, then search on eBay or Amazon for "1.25 eyepiece" and you will find many available. None of these will be made by "Edu-Science", but any make will fit.
The other variable will be the focal length of the eyepiece, which is what determines it's power. The power of the scope will be the focal length of the main objective divided by the focal length of the eyepiece, so a 9mm eyepiece will give a higher magnification (and be dimmer and harder to focus and find objects) than a 20mm eyepiece. It is usual to have two or three different focal length eyepieces for viewing different objects.
You will find a large variation in prices, which is partly due to the difference in quality and type of construction of the eyepieces. Kellner eyepieces are simple and cheap, whereas Possl or orthoscopic ones are more complex and cost more. There are reasons why people will pay more for the better eyepieces. Avoid eyepieces marked with the letters "H" or "SR" before the focal length.
