Tükenmez kalemin dolmakalemden farkı nedir?

Kalemin tarihi yazınınkinden de eskidir. İlk insanlar sivriltilmiş çakmak taşlarıyla duvar resimleri yapmıştır. Mürekkepli metal kalemler Romalılar tarafından biliniyordu. Tükenmez kalem adı ile bilinen bilye uçlu kalemin ilk modeli 1880 yılında yapılmıştır fakat rağbet görmemiştir. Uçakların gelişmesiyle gündeme tekrar gelir. Uçaklar 2-3bin metreye çıkınca  hava basıncı oldukça azalır. Dolmakalem mürekkebi basınç nedeniyle dışarı akarak kağıdı ya da giysiyi lekeler. 2.Dünya Savaşı'nda askeri uçaklarda kullanılan tükenmez kalem sonradan yaygınlaşmıştır. Tükenmez kalemlerde mürekkep kağıda pirinç uçtaki yuvaya yerleştirilmiş minik bir bilye aracılığıyla aktarılır. Fakat dolmakalemin özelliği seçkin ve yazıyı kaliteli kılmasıdır.
