I think those are the berg tubes, not regular tire tubes @frame.b022 . I’d recommend actually switching tires completely. Those meepo tires are very prone to flats.
If it’s just a small hole, you can just patch the tube and get back to riding while you wait for new ones. Bike tire patch kits are super cheap and easy to get.
I always recommend using slime tire sealant and possibly even tube liners if you tend to get a lot of flats from punctures. Both have saved me loads of times.
