ラウンドコースター

At just 5g each, these coasters are so featherlight I almost forgot they were in the box, yet the 9x9cm size covers a mug base perfectly. They’ve already saved my wooden table from a couple of condensation rings, and they stack flat for easy storage.

I wasn’t sure how much difference a 5g coaster would make, but these are so light I barely notice them on the table. The 9x9 cm size is just right for my coffee mug without looking bulky.

Finally, coasters that don't take up half the table space—these are only 0.3cm thick so they slide right under a glass without wobbling. They stay put and don't leave any sticky residue behind.
