Detail 01
.50 mm thickness
Thin. It bends against the strings, which softens attack and evens out strumming volume across six strings.

D'Andrea390 Sharkfin Delrex Delrin Guitar Picks - One Dozen Red .50 mm
1/4
Independent shopping perspective
The Korena take
A dozen thin Delrin sharkfin picks at .50 mm. For strummers who want flex and a pick shape with multiple usable edges.
Strong match
Who this is for
- Acoustic strumming where a stiff pick sounds harsh
- Players who want a pointed tip and a rounded edge on one pick
- Cheap way to test whether thin picks suit your right hand
Consider the trade-offs
When to look elsewhere
- Lead players needing a rigid tip for fast single notes
- Heavy pick fans — .50 mm will flex and slap
- Anyone wanting a grippy textured surface
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Delrin (Delrex) material
Slick, low-friction plastic that wears slowly. Slides off strings easily but can feel slippery with sweaty hands.
Detail 03
Sharkfin shape
One pointed corner plus scalloped edges, so you can rotate for a sharper attack or a broader strum without swapping picks.
Detail 04
One dozen
Enough to lose several and still have picks. Thin picks wear and crack faster than heavy ones.
Detail 05
Red color
Easier to spot inside a soundhole or on a dark stage floor than black or clear picks.
Final check
Know before you order
- 01Thin picks wear at the tip; expect to rotate through them faster
- 02Delrin is smooth — add grip tape if your hands sweat
- 03Not a good match for heavy-gauge or wound bass strings
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is .50 mm too thin for me?
If you mostly strum chords, .50 mm gives a loose, forgiving feel. If you pick single notes or play hard, the flex will fight you — go thicker.
02What is the sharkfin shape for?
It gives you several working edges on one pick. Rotate to the point for a defined attack, or use a scalloped edge for a softer, wider strum.
03How does Delrin compare to celluloid?
Delrin is slicker and more wear-resistant. Celluloid has more surface grip and a slightly warmer click against the string. Feel is the real difference.
04Will these work on bass?
At .50 mm they're very thin for bass strings. You'll get a lot of flex and little attack. Most bass players want something stiffer.
