Mighty Mug Plastic Solo Mug - Pink

It is practical and working

Because of the price (70 euro's), I thought I would get 6 mugs for the price of 5, but it turns out 6x is part of the 3 dimensions of the cup. That's totally my fault, but in case anyone thinks the same way, it's only one, and it's cheaper to buy this locally. It's probably expensive because they ship it from Japan, so I'll just keep it.

I'd recommend you put the lid on if you want maximum spill protection, otherwise if bumped can splash a bit out the top. After spilling coffee on my nice mechanical keyboard I searched for a solution and found this. It works great on a flat smooth clean surface.

本当に倒れないです。叩いて楽しむと言う謎のタンブラー。吸盤が底についてるのですが、横から見ても全く目立ちません。横方向の衝撃にはビクともせず、持ち上げる時などの縦の動きはスムーズ。空気がなんたらということですが、よくわりません。科学ってすげー！！！状態。 ゲーミングデスクに最高。デザインもとても良いです。

Need to reorder- daughter has cracked the lid

This thing is awesome. I was a little skeptical of how well it would work but have been blown away since it delivered. It cannot be knocked over with any normal-style bumping and pushing that may occur. And when you pick up to drink, it lifts of the table with no effort, no lag or tension. It's literally like picking up any other cup or tumbler. Great, great product for my house where the wife to whom I'm married leaves coffee cups 90% drank all over the place and my kids move around w impunity to knock them over.
