ElectroCookie PCB Prototype Board, Snappable Strip Board with Power Rails for Electronics Projects Compatible for DIY Arduino Soldering Projects, Gold-Plated, 3.8"x3.5" (2 Pack, Matte Black)

nicely made. The pads go all the way through, not stuck on, and the boards are modular in the sense that you can leave them attached together for a larger project or split them up for smaller ones. You can even span two boards with an IC because the holes line up where the boards join - there's no gap. They also look nice.

Holes were the right size for my pins and soldering was easy 17/17 stripboard.

フライトシミュレータの自作IO用に使用．　ほとんど初心者なので失敗を繰り返しているがやり直し（ハンダ付けし直し）しても耐えてくれる．　JST　XHコネクタを裏表それぞれに取り付けて装置のブロック分けに使用．　4分割の1枚で使用する事が多い．　3セットリピート買い済．　姉妹品のMini6Pも同時購入したが、当方の使用目的には小さく待機中．

I love these little boards. They're high-quality and I find the groupings of three connected holes to be very useful for the type of projects I'm working on.
