Look over garden walls or peep around corners without being seen! Check out wildlife, discover hard to reach places or get a closer view at a football match. There’s lots of undercover fun to be had (though we don’t condone spying on your neighbours!).

Lightweight and ergonomically designed with a wide viewing area and extendable telescopic tube, this innovative Periscope will open a whole new world.

Easy-grip handles make the Periscope super easy to use. Two high-quality mirrors ensure a bright, sharp image; also comes with a safety cap to protect the mirrors.

Straightforward to assemble using slot together techniques – there’s no glue, no mess, no fuss. Everything you need is provided in the kit – simply follow the instructions: press out the pre-cut parts, build and you’re ready to explore!

Stealth black with metallic silver detail, this fully functioning Periscope is sleek in design and will look great on the shelf when not in use.

Our Periscope is suitable for children 8 years+ but is best enjoyed as a family experience.

Made using sustainable cardboard, Build Your Own’s Periscope is not only fun and engaging to play with, but also eco-friendly.
